Our home is on a private well system where the water is particularly hard. I have had my washer for about 3 years and more often than not, the pressure coming out of the washer is inconsistent. When using the Karcher Rotary Nozzle, the water comes out as a stream when the trigger is pulled. Numerous pulls of the trigger later, something will change or "let go" and the pressure is correct and the nozzle works as long as the trigger is kept depressed. I don't know if there is a calcium buildup somewhere in the machine that is causing the inconsistent pressure or if there is another reason for the low pressure. Using the other nozzles has the same results, low pressure, numerous trigger pulls, finally the correct pressure as long as the trigger is depressed. Is there a water filter on the machine that can be cleaned or replaced or is something else wrong? Thank you in advance for any help you can offer.

The customer rating on this product at Lowe's is 1.5 stars out of 5. It is electric & operates on a series of pressure sensors and valves.I don't use electrics because There is no way to protect or lubricate the internal mechanisms from hard water sources. My guess is your machine jammed up as a result of hard water leaving residues on a switch, valve or sensor. I also learned many of the Lowes customers found no customer service for this item which leads me to believe it is a private labeled(made just for a limited store sale) machine fabricated in either Mexico or China. Your best recourse is to trash it and purchase a gas powered one with a CAT style pump(not mounted under the motor) in the future. Also, do the maintenance. These things need to be completely emptied of water after each use and lubed with a product such as "pump saver" and the fittings & triggers need to be sprayed with WD-40(it displaces water). If not they will clog, seize, corrode etc. If these "do all" pressure washers they are selling at Lowes & Home Depot with all the attachments were any good I would have bought 4 instead of spending the money I did on my set up. Sorry to be the bearer of bad news.
I have same model with same problem. Tried the easy fixes: unloader valve lube and clean, inlet water sufficient, and nozzles and hose are fine. Broke down pump and called for parts (about $50 for 3 inlet valves and some seals) hopefully this will fix it. Mine has been used in my business pretty hard for a few years, so not bad. Joebro
Chances are that your new pump is generating good pressure. Because of this, the engine is trying to turn over against the pressurized system. Try pulling the handle on your wand when pull starting the engine to see if this eliminates your problem.
I have a Troybilt Model 2200 PSI Pressure Washer in which I have used only 2 times in the past 2 1/2 years. Went to use it this past weekend and the pump in not working. Water shoots out of the side. I bought this brand and model as I thought Troybilt was suppose to be so good. Went back to where it was purchased and had no success but to say I could buy another pump or take it in to be repaired. I believe that this power washer should be replaced at no charge. 2 uses does not constitute a few hundreds of dollars.
Have you to heard anything concerning pump problems on this particular model? Thanks for any advice. .
If the water fill time exceeds ten minutes, the water valves are turned off and LF is flashed.

You will need to check you fill hoses this is 95% of the problem in the rear of the unit ther are two hoses Hot and Cold feeds shut off the water and Unplug the unit Then remove the hoses from the machine. in the Valve where the hoses go to there are little mesh screens they are most likely clogged take a eyeglass screwdriver or paper clip and hook the screens pull them out carefully and clean them reinstall and connect hose and test
