We barely know how to use a pressure washer, but we don’t care about its health. Last month, I was doing home service at Mrs. Janet’s house in Detroit City, Michigan. She was distraught that her busy Landa pressure washer machine was malfunctioning, and she was having trouble cleaning her family’s clothes. We all think, like Mrs. Janet, that since it is a machine, it has no rest except service. Indeed does not need to be taken care of. But if the question is, how many times a month have you cleaned the dirt from the heating coil of your Landa pressure washer machine?
I know, most users don’t know about this answer. Where Landa is not aware of the pressure washer machine, how to do pressure washers troubleshoot? A machine can take care of your family every day, but you cannot take care of it one day in a month. That is a very normal thing; it is challenging to find time in a busy life. Yet, a user should know the problems and solutions of the Landa Pressure Washer. I will discuss here the troubleshooting of some of the common issues of the Landa washing machine.
Landa Pressure Washer Troubleshooting:-
Nowadays, pressure washer machines have become as important as other necessities in human life. Everyone tries to keep the house, garden, and yard clean and tidy. Landa Pressure Washer not only cleans but also saves the owner time. Arrange for proper maintenance for long-term use.
It is normal to have problems with pressure washers as a result of long-term use. If you have proper knowledge about the washer, you will quickly deal with the situation. But if you do not have the minimum knowledge about the washer, you will not be able to catch the problem; the solution is far away!
Now I will discuss some of the problems and how to solve them more simply.
Keep Washer Free From Freezing:
When the temperature drops below 0 ° (32 ° Fahrenheit) Celsius, the Landa pressure washer freezes in wintertime. Freezing can cause problems in different parts of the washer. Keep the washer in a warm place to avoid such damage. If this is not possible, mix 50 percent water and 50 percent anti-freeze solution and pour it into the float tank. Now turn on the engine and make sure that the anti-freeze mixture is going through the machine. If there is compressed air in the float tank, install an air fitting. In this way, water will come out of the machine through the spray gun. Remember, the company never offers warranty services for frozen damage.
Inspection Of High Limit Control Switch:
If the hot pressure washer machine’s water temperature exceeds a specific limit, it destroys the heating coil. A high limit control switch is attached to each pressure washer to avoid this damage. This switch automatically shuts off the burner switch when the water temperature rises until it cools down. It is usually located on the discharge side of the heating coil. So monitor the high limit control switch properly and repair it if there is any problem.
Cleaning Of Heating Coil:
Due to the growth of dust in the heating coil, its temperature rises. The expansion of lime in the alkaline water path makes the heating coil more inefficient. Always use the best quality detergent to avoid this. You can use Landa liming powder to solve the problem in alkaline water lines. That easily removes lime and protects the coil from being plugged.
Mix 1 lb of Landa liming powder with 3-4 gallons of water and pour into the float tank. Place the spray gun in the float tank, leaving the trigger wind of the spray gun open. Now start the engine and bring the mixture back to the float tank through the coil. Keep doing this until the color changes. Rinse the entire system with clean water after a particular time. Thus remove the lime from the heating coil.
Adjusting Fuel Control System:
Fuel solenoid valves are attached to each Landa hot pressure washer to control the fuel flow level. It stays closed under normal conditions. The flow switch turns it on at the time through the water flows. When the spray gun is turned on, the flow of water with the flow switch is stopped, and it shuts off the power supply to the solenoid valve. In this case, the solenoid valve shuts off the fuel supply to the combustion chamber.
If the fuel solenoid valve does not work correctly, the water will mix with the water. Due to this, the combustion chamber will catch fire. Check the solenoid valve every time before turning on the washer. If a problem is detected, change quickly. If you do not have a complete idea about this, contact the Landa Service Center and seek an experienced person’s advice.
Water Pump Troubleshooting:-
The spray gun does not get good water even though there is enough water in the pump because the pump leaks or dirt accumulates in the water flow line. To overcome this problem, first, check if there is enough water in the pump. If there is no water, arrange the necessary water. Now check if there is any leak in the pump. In case of leakage, close it with essential material, change the pump if possible.
Finally, check if there is dirt in the water flow line inside the pump. To clean the dirt from the water flow line, wrap some cloth around the head of a stick and clean it by turning it well. This type of problem will frequently happen if the pump is too old. So Need To replace the pump after a particular time.
Install A New Gauge:
After a long period of use, the gauge gradually becomes ineffective. The ineffective gauge cannot put enough pressure on the pressure washer machine. Apply a new gauge after using it in a few steps to get better results. Moreover, if the old meter is clogged, remove the dirt from it.
High-Pressure Hose Troubleshooting:-
If the high-pressure hose leaks or air enters, it fails to pressure the water flow. High-pressure hoses play an influential role in creating pressure in the water flow. So mark the leaks as soon as possible without delay and close them. Please turn on the water-filled pump by removing it from the spray gun to expel air from the pressure hose. Keep the pump running for 4 to 5 minutes. Be sure to turn off the engine when air is released from the high-pressure hose.
Over time, dirt accumulates in the hose filter, preventing water from flowing. High-pressure hose filters are susceptible. Therefore, when removing dirt from the hose filter, make sure that the filter does not break. Gently clean the filter by mixing the liquid chemical with the cloth. Contact the local Landa Washer Company for replacement and arrange a hose of a specific size.
Proper Use of Fuel:
Check the amount and quality of the fuel before using the pressure washer. After 100 hours of continuous running, replace the old fuel with new fuel. Old fuel can be clogged or evaporated. In this case, the burner nozzle does not get good energy, interfering with the washer’s overall operation. Always keep the fuel level at the desired level for the pressure washer to work smoothly.
It is often seen that the fuel is mixed with water. The water-mixed fuel drives the machine roughly. Contaminated fuel disables hose, nozzle, spray guns. Therefore, before pouring fuel into the tank, drain the fuel tank and remove the fuel filter’s dirt.
Be Careful About Worn Out Electric Wire:
Dilapidated or leaking electric wire causes damage to the user. Keep the pressure washer at a minimum distance from where you will be cleaning so that water does not touch the washer wire. Before you work, check the electric wire carefully to see if there are any leaks. Arrange new wiring by replacing the worn one and try to keep it shiny at all times because the worn-out wire is unable to give proper voltage.
Inspect Unloader Valve Functions:
The unloader valve is an essential component for pressure washer machines. It works in a pressure washer in two ways. An unloader valve increases the flow rate by releasing the spray gun’s trigger and creating pressure on the water flow.
When the trigger spray is turned off while the engine is running, the unloader valve bypasses the water back to the pump. Based on the dual function, it adjusts the work of the pressure washer.
If the spray gun does not get proper pressure despite having enough water, then the unloader valve is damaged. Remove the valve from the washer to understand the problem. Replace the broken unloader straight away without the folly of repairing it. Rub with a wire brush to remove dirt from the unloader, then clean with clear water.
Take some personal precautions when using pressure washers to avoid danger. Use ear defenders to defend the ear from noise pollution if it exceeds 85 decibels on the machine. Refrain from using combustible liquids to clean any part of the washer machine. Do not change the fuel while the machine is on. Also, read the usage guidelines provided by the company.
