Turn water on then actuate wand trigger. Pressure washer leaks when wand trigger is actuated and has very low pressure/flow output. After releasing trigger the pressure cycles on - off at approx 1 second interval. I suspect that the plasstic oulet tube is leaking causing low pressure leak out of bottom when trigger is actuated and causes pressure switch to cycle when the trigger is released. Any Help? This pressure washer is approx 18 months old!

I have a Bosch Dishwasher Model # SHU43C that is not washing properly. Some dishes are not being cleaned if we don't pre-scrub or rinse. There are no error codes on the panel. During the cycle I hear the pump motor starting and stopping repeatedly on about 1 second intervals. I suspect it may be starved for inlet water. I checked the inlet water line and it is clear. We use well water that occassionally has some iron sediment in it and it plugged the inlet water screen for our washing mach


Hi,\015\012It is very possible that the screen is plugged...most inlet valves have a screen just like your washer does. I would at least remove the hose/pipe and check the flow...and check for a screen. \015\012Also the solenoid can get j ... Bosch 24 in. SHU43 Built-in Dishwasher

I changed the setting to unselect Hi Temp Wash but don't remember if it was selected before. The next day the dishwasher filled as usual, washing started for about 4 seconds, then stopped for aroud 10 seconds. The start/stop cycle repeated about 4 times, then all lights went off and nothing more happened.

When it calls for a drain cycle it sounds like the motor tries to start for half a second and then the display blinks and there is a click. This repeats every few seconds until you open the door. If you wait 15 minutes and close the door it will click once and then drain fine; until the next drain cycle.

I have a Generac pressure washer, model #01450-0, with a Honda 5hp motor. The motor runs fine, but the pressure hose pulsates as if the pump is intermittently making pressure, and the pressure out of the sprayer is about half of what it should be. A friend suggested replacing the seals in the unloader. I bought an unloader kit, replaced everything and it still runs the same. It will build a small amount of pressure, spray for a few seconds, then the pressure dropps to almost nothing. Any help ap

How do I fix a pressure washer that will not build up pressure quickly and when it does reach high pressure, the pressure quickly drops to a lower pressure (more typical of the pressure found in a garden hose)

Whirlpool dishwasher doesn't seem to fill with enough water despite good water pressure. Therefore, pump sounds like it is cycling from pumping water for about 2 seconds to going dry for 2 seconds to pumping water for 2 seconds to going dry for 2 seconds, etc. Spray arms rotate only for the 2 seconds when pump is actually pumping water. Dishes do not get clean.

Asko Dishwasher starts the cycle by pumping out as it should. But does not stop pumping nor advances. If I click it forward manually it starts to fill and then before overfilling goes into pump out without washing then just repeats this.
