If there is nothing wrong with the machine but you have lost power over the years you have been working it. It could be that the machine needs a new pump kit or/and change the pressure nozzle.smaller issues could be that the pump isnt turned to high pressure or if you have an servo control on the gun that it is turned to low pressure instead of high pressure.

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

You may need to rebuild or replace the pump assembly. If the pump is more than a few years old, and you use the pressure washer fairly often, replace the pump assembly. If the pump is relatively new, and you don`t use the pressure washer often, either rebuild the pump assembly or replace the pump seals.
What should I do if the steam cleaner does not heat up? Check the power cord and fuse, as well as the thermostat and pressure switch. Top up the water. If the water shortage light does not go off, please consult one of our service partners or contact us directly.
Fill the Tank With Vinegar: Fill the water tank with distilled white vinegar or cleaning vinegar. Allow the vinegar to sit in the tank for at least 30 minutes (up to two hours is best) to help break apart the limescale and mineral deposits. Expel the Vinegar: Turn on the steamer and choose the highest heat setting.
PLEASE NOTE: You should always press the RESET button on the GFCI before using the pressure washer.
If you have hard water and have never cleaned your steamer, you may be surprised to discover all of the mineral deposits that are collecting inside the appliance. The worst part: the mineral buildup can start to clog the steamer, and could even leave white chalky stains on your clothing.
Using an old, worn-out nozzle is a common cause of lost pressure, and also has one of the simplest fixes. All you need to do is replace the nozzle and make sure you`re using the proper size. Don`t go by the color of the nozzle, make sure you check the orifice size.
If the machine is pulsing whilst in use, it may be that the accessory you are using has a blockage. Clear by soaking the accessory in warm soapy water and then rinsing out under the tap.

No pressure Pump reassembly. I purchased a new pump and installed it. Got machine back together and I’m not getting any pressure. What would be the signs if I don’t have the shaft key in properly? Or any other suggestions?
