I am no electrician but open black plastic case and check capacitor .If it does not show burnt signs then smell it to see if its burnt.It could be a number of other things if it is not a capacitor.
remember to short the terminals on the capacitor with an insulated screwdriver . a capacitor sort of acts like a battery and can sometimes store a nasty charge .BE careful or have a sparky check it for u .They should not charge u much to do a 5 second test with a meter

Motor seized up! You can try turning it manually. If it moves freely then yes motor has burnt out! If it has resistance, try turning it until it moves freely then try to run the washer! Best of luck

My karcher k7.85 has lost pressure and the motor runs constantly when switched on ,motor only used to run when trigger pulled in on lance ,there is no leaks. Can any one help please.


Sounds like the pump seals are bad. The manual says to only use these a few minutes at a time, most people try to clean the patio etc with them, run them too long, and burn out the pump seals - don't ask me how I know this.

Karcher K2.94 intermittent pumping and buzzing


try the machine with the lance removed from the gun.

buzzing is usually the noise made by the motor when it cant turn. if the pump start to pruduce pressure but the pressure builds up too high then the motor will stop turning... faulty lance or faulty spill valve (dump valve)

If you have a Karcher then you should always post your machines barcode.
The karcher barcode is on a silver sticker and is usually 15 digits long. Example 156987400000123 is actually model 1.569-874.0 and serial number 00123....

The water must be switched on, and seen to be running freely from the nozzle for a few seconds before switching on the power - suggest you check the fuse in the plug, and then try the above.

Karcher K2.36 motor cut out and won't restart


Yes, the water should be turned on first but if it only ran for a minute or two it should be OK. Most late model pressure washers have an automatic shutoff when the trigger on the wand is released. Turn on the water and then the machine and then squeeze the trigger on the handle of the wand and the motor should start as soon as the air is cleared from the line by the flowing water (about 10 seconds). If the unit was put away wet last season you may need to clean the nozzle with a piece of wire too.

you have an electrical short in the motor windings. you'll have to either replace the motor or buy another washer. also check to see if the motor isn't locked up with a piece of trash. to do that you'll have to dissassemble housing until you get to the motor. it should turn easily by hand. if so you have a short.
