Power stick has water coming out sides instead of out the end

at the end of the season do you run the water out of the pump. the reason that I'm asking is the pump may have a crack in it . to were the pump maybe losing water

your video doesn't show much of your shower for very long, but at a guess i'd say you have separate hot cold taps, in which case always turn on hot first then carefully turn on cold to ensure there's no issue with water pressure. if there no hot water running at all the hot water valve is faulty

Hydraulic oil?
Is this a pressure washer?
Pump should be half full of SAE20 or SAE30 non-detergent motor oil.
Engine should have 10W30 motor oil.

If you have a pressure washer ... and not water is coming out end of gun:
Take all hoses off machine.
Look at incoming water hose connection.
The should be a filter washer.
Clean or replace filter washer.
Hook up water and turn on water.
Water should come out other side of pump.
Turn on power washer and see if water coming out of pump is pressurized.
Now hook up pressure hose without gun.
Turn on pressure washer and see if water comes out of hose and is pressurized.
Finally, the gun may be bad.
We used to replace guns when they went bad.

If it fills with water and starts the cycle and the water keeps running in then your water inlet valve on the back where the water supply comes in is sticking. It needs replacing. The cold side can fail independently of the hot side.

start by making sure the valve that supplies hot water to the sink and dish washer is fully open. If there is low hot water pressure in any of the other kitchen/bathrooms, then trace the line to see where the pressure drops. If it is only in the kitchen, it should be an old valve, (causes restriction)Good Luck.

Pull disp out. Check to see if its clean. Put into sink and run a sead stream of water into bleach cup till overflows and syhpon tube begins to drain water. Turn of spicket while holding disp steady and level. If the water drains cold water valve is faulty or screen is restriced reducing water preasure. Poor water preasure will prevent proper syhponing. If disp doesn't syphon or drain water out while in sink its either faulty or dirty.

Hi, If you remove the screws on each side of the door opening, the front panel will come free. You might be able to lok in and see the preasure hose. Id the hose leaking or the cup it attaches to?
I hope this helps. Please let me know if I can assist you further. Thanks

possible fill valve is sticking open when filling after starting washer disconnect power and listen to see if water is still running in if so replace fill valve.. if water stops possible water level switch or small hose to switch plugged ..drain washer remove screws on each side of door frame front will pull off...small hose on some models was attached to pump housing and would become plugged with lint ckd for restriction in hose from bottom to top remove screws in console to acess other end attached to pressure switch

check your pressure switch
