How to Diagnose Pressure Washer for Freeze Damage
While it is evident that subpar temperatures affect the optimal functioning of pressure washers, if not wholly damaging them, we do not encourage assumptions. It would be best to comprehensively diagnose your machine to ascertain the cause of the damage.
Pumps, for example, may work less effectively because their oil has thickened. Moreover, motors in pressure washers may halt because of residue from detergent oil going through a faulty filter. It would be best not always to assume that a filter in your washer is effective.
Especially if you have not recently replaced it with a new one. Overused filters often let unwanted particles enter the engine system, wreaking havoc on the machine. When it comes to diagnosing your power washer for freeze damage, here is a simple procedure you should follow:
• Check the hosepipe:
After leaving your pressure washer in the cold for a few days or weeks, diagnosing it for freeze damage is vital. You should note that water in hosepipes can freeze almost instantly in freezing conditions.
Thus, storing or using your washer in a warm bay/garage allows thawing, which is vital. After a few minutes, the frozen water should be changed to liquid.
One common misconception I’ve encountered is the belief that simply draining the water from the pressure washer will prevent freeze damage. However, removing all water from the pump is nearly impossible, and any remaining water can still freeze and cause damage.
• Turn the engine on and check for damage:
The next step is switching on the power washer. With the pressure washer running, please pay close attention to the strange sounds its engine and pump produce. Do you hear rattling/humming? These sounds often signal freeze damage.
It is also very likely that the machine will shut down after a minute or two. An electric circuit may strip, mainly when using electric pressure washers. Sometimes, a fuse may also blow, indicating that the machine is adversely damaged by exposure to subpar temperatures.
• Perform the repairs:
Should you confirm the above signs of freeze damage, do not use the power washer. Instead, shut it down and take it to a servicing center for repair and maintenance. It is noteworthy that while freeze damage may not render your washer useless, manufacturers are very skeptical about their warranty provisions.
Repair and maintenance due to freeze damage are hardly one of them. Often, the buck stops with the owner. If you always maintain your machine to prevent unprecedented damage, there is no cause for alarm.
However, not knowing how to winterize your power washer, something we look at next, will push maintenance and repair costs higher than necessary. In the worst situations, you may buy a brand-new machine when a washer breaks down beyond repair.
How Do You Winterize A Pressure Washer?
Freeze damage in pressure washers can be catastrophic depending on the extent of frozen water in the pump, hosepipe, and other components. Everyone should answer the following question: how best to winterize pressure washers?
First off, note that winterization is a process that involves preparing pressure washers for cold weather, especially during winter. You should also perform it on other machines, such as lawnmowers.
• The Impact of Subpar Temperatures on Your Power Washer
Understanding that subpar temperatures will damage your power washer machines makes you a step closer to doing the right thing. You don’t want to take chances.
Winterizing becomes necessary when people living in areas that experience harsh winters hardly use their pressure washers during the cold season. You cannot avoid it and realize the optimal performance of your cleaning machine.
Tips on winterizing the motor
You don’t want the motor in your machine to become inoperable after winter; hence, winterizing it means you should do the following:
– Add fuel in the tank:
Ensuring water does not condense into the gas lines leading to the motor and gas tank is the key to keeping pressure washers operable throughout winter.
Always fill your gasoline-powered tank with fuel. We also recommend using a fuel stabilizer. However, it would be best if you did so based on the manufacturer’s guidelines in the user manual.
– Run it for a while:
Secondly, please turn on the power washer and let it run for a few minutes. The catch here is to ensure the proper circulation of water throughout the pump system. It also provides the fuel stabilizer to reach the carburetor, gas lines, and gas tank.
In my 20 years of experience, I’ve seen that the immediate effects of freezing on a pressure washer can be quite damaging. The water inside the washer expands when it freezes, leading to cracks in the pump and other components. It’s a common issue many overlook until it’s too late.
– Drain the fuel from the tank:
Another way of winterizing the motor is by draining all the fuel from the machine’s system. Following the manufacturer’s guidelines in your user manual would be best.
– Use oil for lubrication:
Because pressure washer engines work slowly and become inefficient during winter, you should lubricate the engine, cylinders, and carburetor to keep them working optimally during and after the cold season.
Most importantly, you should use clean oil. For the best results, change the oil regularly, preferably after every 200 hours.
Tips on winterizing the pump on your pressure washer
You should, of course, winterize the pump too. To do so, we recommend doing the following:
– Drain the cleaner residues:
Start by draining the residue of a cleaning detergent/solution from your power washer’s system. Hold the trigger on your washer while the injector is in a water-filled bucket. For power washers that have pre-pump injectors for detergent, turn off the water inlet and the engine.
– Remove any water:
Pulling an engine starter cord on your pressure washer ensures no water remains in the pump. While doing so, disconnect pressure and water hoses.
– Preserve the pump components:
Preserving power washer pistons, seals, and manifolds is another important winterization task on your machine. If you do not use it throughout winter, lock these parts inside a pump screwed to the water inlet.
Alternatively, you can screw the pump saver to the point at which a garden hose gets connected to the pressure washer.
– Using a pump saver:
For homesteaders who do not know how to use a pump saver, contact your manufacturer for the best advice on the machine’s anti-freeze flushing.
– Use additives:
You can use pump fuel additives to preserve the machine’s integrity, mainly if you use it during winter.
– Store in a cool, dry place:
Lastly, storing a power washer in a cool and dry room saves it from winter frost.
More Tips on Winterizing Pressure Washers
Winterizing power washers do not stop with stabilizing fluids in the machine or lubricating its movable parts. Taking into consideration the above tips, here are more practices that will preserve the structural integrity of your handy cleaner:
Over the past 20 years, I’ve learned some unique tips to protect pressure washers from freezing. These tips are based on my personal experiences and have proven to be effective time and time again.
● Keep the washer in a warm room
We know performing an anti-free procedure on your pressure washer all the time can be time-consuming. Thus, you may want to try other methods of winterizing it because the pump is the most susceptible to subpar temperatures.
Often freezing at the slightest temperature change, we recommend keeping it in a warm room. But first, you must disconnect the washer and hose from the drain. This is because hosepipes expand and may crack when temperatures fall below zero degrees.
● Seek professional help with winterizing
You may want to schedule pressure washer winterizing and other maintenance routines, and that’s okay. It is indispensable if you plan to use your power washer throughout winter. While winterizing the machine is something you can do at home.
Seeking help with the exercise from professional service providers comes with many benefits. First, they will evaluate your gadget and recommend maintenance practices to improve its structural integrity alongside winterizing.
Secondly, they will charge you less, especially if the repair falls on the month of annual power washer servicing. For first-timers using pressure washers, a quick web search should pull up results on winterization services near you.
● Keep track of temperature changes
During winter, when temperatures fall below zero degrees and the frost makes it challenging to clean pavements, you can still use your pressure washer. However, we would advise that you only perform cleaning duties from midmorning to late afternoon because that is when the temperature is friendly.
It would be best not to use a pressure washer when the cold is unbearable. However, if cleaning is urgent, we recommend putting money into a good washer that uses warm water. Many warm water pressure washers are on the market, but let’s reserve that for another topic.
Using Your Pressure Washer during Cold Season: Practical Tips You Should Know
Learning how to use homesteading machines like pressure washers when temperatures fall below the freezing point is essential. The cold season often comes with risks, most of which threaten the health of engines/motors. Moreover, the harsh weather itself is a threat to your health.
Thus, apart from wearing warm clothing to guard against contracting hypothermia, you must do the right thing when duty calls. Now, note that pressure washing in freezing conditions has many challenges; you don’t want to take chances.
For example, clearing ice from your car’s exterior is only possible if you work smart. While adding salt to ice on roads works most of the time, it also risks your pressure washer and car.
• The Role of Pressure Washers in Winter Car Maintenance
If your car does not rust with continued exposure to salt on roads, its door and window may become challenging to open/close because of ice.
Thus, a pressure washer becomes a great alternative to cleaning icy driveways during winter. But before getting started, take note of the following pressure-washing tips for the cold season:
● Work indoors
Working indoors will save your power washer from freeze damage. You also stay safe from hypothermia. If you have a home garage, insulate its interior to keep you and the machine safe against the cold.
However, for those who do not have garages, constructing a wash bay should only take a few easy DIY steps. You can also hire a service provider to make one in no time.
● Always de-ice
De-icing driveways using sand or salt is crucial when using pressure washers outdoors during the cold season.
However, it often leaves behind a slippery surface. Hence, you must be extra careful when using your washer indoors to de-ice clean water that splashes onto concrete driveways, lest you end up with an even trickier icy situation.
● Warm water in the resource
While you can still use relatively cold water to wash your car or clean driveways during winter, you should not risk doing so when temperatures are extremely low. You should warm the water a little to guard against the risk of it freezing within the hosepipe.
If water from outdoor taps/reservoirs is freezing, connect the hosepipe to an interior one. The ideal water temperature for pressure washing during winter is 180 degrees. However, it should not exceed 200 degrees.
● Use winter-friendly cleaning chemicals
Home and car cleaning detergents vary based on chemical composition. Thus, you should seek help finding the best winter detergents for pressure washers. A quick online search should get you some leads.
● Aim the nozzle appropriately
You should not splash water haphazardly when pressure washing during winter. If, for example, you are washing your car, shut and open its doors in winter often. You don’t want to end up struggling with opening your car window after a cleaning routine because of the frost.
● Lubricate pressure washer wheels
The wheels of a pressure washer are often the culprit of freeze damage. And it could get worse when using the machine outdoors. Therefore, we advise you to grease the wheels to guard against water freezing in openings and cracks.
● You should ensure a steady flow of water in the pipes
Using pressure washers in sub-zero temperatures is very tricky. You drop the hosepipe onto the ground; the water inside freezes almost instantly. Thus, to avoid such a situation, ensure a steady flow from the reservoir.
● Use the proper nozzles
A zero-degree nozzle is the best for washing ice off your car in subpar temperatures. First, use it to cut large ice blocks on the car’s exterior, then blast smaller pieces with pressurized water from a power washer.
● Apply wax on surfaces before cleaning
Waxing off or applying wax on surfaces before cleaning during winter comes with two main benefits. First, it protects painted surfaces. Secondly, it facilitates faster drying after washing. Your detergent supplier should recommend the best spray wax.
Remarks
In a nutshell, using pressure washers during winter is often very tricky. You face the danger of contracting hypothermia and the risk of losing your machine to freeze damage; however, with tips in this post, including knowing what happens if a pressure washer freezes.
It would be best to do the right thing at the right time. Winterizing machines, which technically prepares them for the cold season, is the best thing to do. When using your pressure wash equipment during the winter, it’s essential to consider the Freezing temperatures.
Failure to do so can lead to severe damage. Dust, elements, and corrosion are just a few factors that can spark problems. Understanding how your machine operates can help prevent these issues. Rodents and other small creatures may seek shelter in your machine, causing damage.
• Preventing Pests and Freezing with Anti-Freeze
Consider using a fluid or a small amount of anti-freeze in your pump to prevent this. This will not only deter pests but also protect pump equipment from freezing. Before storing your machine, make sure to blow out any remaining water. This is a crucial step in maintaining your machine’s longevity.
Storage in a dry, warm place is also recommended. Many resources are available to learn more about how to winterize a pressure washer and how to winterize a pressure washer pump. Remember, following these steps is essential to use your machine when needed.
Lastly, permanently remove any remaining water and disconnect the battery before storage. This will help prevent unwanted surprises when you’re ready to use your machine again.
