I have a KARCHER Model K 2401 which onstart up has normal water pressure rather than the high. I can usually get it to work by removing the tip, pressing the trigger and running some water through without the tip on. The i replace tip and it will usually retain the high pressure. If I stop depressing the trigger I have to go through these same steps. It is like it loses prime. It works well once I get it started putting out the high pressure.

I have a Briggs & Stratton gas power washer. This is the 1st time this year that I have used it. I put in fresh gas, hooked up the water supply. The engine started and then quickly stopped. I had to release the water pressure in the hose before I could pull start the engine. The only way to keep the engine running is to hold down the spray nozzle trigger. Once that is released the pressure in the hose builds up and the engine stops.

My karcher hds 745 is running but just won't build up pressure, this occurred after a really cold few weeks this winter and I hadn't put anti-freeze through the machine to winterize it. There's no water coming from the bottom of the machine when it's running as i've read that if the pump seals are faulty water will escape from the pump etc. The machine motor runs ok but no pressure is acheived on the gauge whatsoever. Any help would be appreciated. Thanks in advance Paul.

Hi. I have a Briggs & Stratton 2800PSI gas pressure washer. I can get it to start, but after about 5 min, then it quits. I have cleaned the carb, change oil, changed plug, new gas, cleaned/checked air filter. Nothing will keep it running. Wondering if it may be not enough water pressure, but would that cause it to stop like that? When it runs, it does a good job, but it stops just as you get going. Do you have any other suggestions? Thanks!

The top drawer of my fisher paykel dishwasher stops during the cycle and shows an icon of a tap with a line threw it (assume that means no or low water pressure). the bottom works fine so I assume water pressure is not the issue; is there a sensor that could be bad? Also, I did switch the controllers between drawers (good instructions on the fisherpaykelparts.net website) but the problem stayed with the drawer, ruling out the controller.

We have a Katcher HDS 3.5/30-4 M Ea. Was using it, stopped using it briefly in the middle of a job, pulled trigger again, and there was a lack of pressure. Went to the machine to troubleshoot. The "engine indicator light" is on. Checked the temperature of machine: fine. Water intake: fine. We have not been running it at high temperatures, but about 50 degrees C. The pressure was at about 2300 PSI before it stopped. Any ideas?

My Siemens dishwasher SE65M350EU/70 has an error about once a week: it washes perfect but during the last step (rinsing/drying) it sometimes stops/ continues a number of times and then indicates a low water pressure error. But never during the other steps of the washing cycle. To me this indicates that the water pressure is correct. Any idea?

I have a Kenmore dishwasher model #17519200. I loaded it last night as usual and closed the door. I pressed the wash cycle I wanted and pressed the start button. I heard it starting to fill with water as usual. After it filled with water it should have gone into the wash cycle mode but it just started making a buzzing noise for about a minute or two then just stopped. I pressed cancel to drain it and it drains fine. I have kept trying to re-run it but it just does the same thing I described.

My Karcher K3.48M pressure washer remains in the low pressure mode even when I return the pressure nozzle to the high pressure position. How can this be corrected.
