Answers :

Most likely problem is that the tip is too small causing Unloader to bypass or restriction/debris in tip. Install clean tip of proper size or 1/2 size larger (example from 2.5 gpm to 3 gpm ) to prevent slow pulse. If tip is clean and /or larger tip does not help, Unloader may be failing if the unit has a good deal of hours or if machine is left running for long periods of time without spraying. Try lubing the internal parts by removing both hoses and installing a short piece of water hose to intake and slowly inject light oil into pump by pulling on the rope slowly to **** in the oil until it comes out the pressure side. This will displace all the water from inside the pump. Leave overnite. There is a kit sold on ebay to help facilitate the infusion of oil but no need to get fancy. Unloader repair kit is usually available if all else fails and is easy to install. Good holidays

I have a Delonghi dishwasher, it's a stand alone, like a washing machine. The water inlet is connected to the hot water tap, normally used for a washing machine. When we first started using the dishwasher, we kept getting the E4 error message, we reduced the water inlet pressure by turning down the tap, that worked for a while. Just a while ago, we started getting the E4 error message again, not sure we can turn down the tap any further without cutting the water off completely. Do you have a


The E4 error message could be because the water pressure is too low rather than too high. Can you let me know the exact model number of your dishwasher and I should be able to tell you more.\015\012\015\012Regards,\015\012BElectric ... Dishwashers

Champion dishwasher we have a champion freestanding dishwasher at my church. after the cycle is completed, the pressure guage behind the washer still shows 25-30 and it contnues to spray water. not forced by the motor, but more like a stuck open fill valve. if i turn off the water and run it, then turn the water back on, the valve is closed and does not let water freely in. butif i run it with the water on, it will continue to spray in freely after the cycle light goes out and you open the door.


If you turn the unit off from the circuit breaker will the water still run?if so the guts inside the solenoid valve are worn.you can call champion and get a kit to replace the worn parts and its not difficult to do.hope this helps. ... Dishwashers

My Karcher 4000 SHR Pressure Washer pressure pulses when operating. I have checked with Karcher Technical Support and all their trouble shooting procedures except checking the unloading valve. Where is this valve, how do I get to it and how do I lubricate it?


It sounds like your unloading valve is crudded up with mineral deposits and stuck in a partway open state. look for a plastic cover with a silver snap on top; pry off the silver snap and lift off the plastic cover; next remove the two screws on the ... Honda Karcher G4000RH Pressure Washer

I have a EuroTech dishwasher Model# EDW254E/SB. It was working fine but now it gives the Err code:er1 Its not letting incoming water in i know that.

I am presuming there is a valve of some sort not opening? And does the dishwasher have to be completly romoved to fix. Thanks

I have a SMEG DWF614 SS dishwasher. I continue to get an E8 error message. The diverter valve motor turns freely & the motor turns freely when they are seperated. However, when they are assembled, the motor turns the valve & continues to try turning the valve when the valve is on its stop position. Is the motor & valve faulty or is it the control. If you can answer, what part number would I require. Regards Leighton Davies

I have a G2500VH pressure washer that has started to pulse when the trigger is squeezed. This happens if I use the 0,25, and 40 degree nozzles BUT if I use the one for low pressure(detergent use) it will hold pressure fine. I have changed the unloader valve, checked all the valves and seals ad they seem to be fine. What could be the problem?
