How to fix on/off switch assembly on kaercher pressure washer 79c2

The plastic on/off panel that one presses (part of the plastic yellow top assembly of this model) is broken ... machine itself worx. Need the black on/off part that inserts into the yellow plastic top housing. Could also need the actual on/off switch since it operates roughly (but that is secondary). Really need the black plastic top plate that touches the internal on/off switch. Suggestions welcome. Thx/rgds - Jack

SOURCE: Wahing machine overflowing

Water does not enter the pressure hose, air does.
Remove the plastic tube from the air dome on the side of the washer. Use a small piece of wire and clean the soap scum out of the air dome hole. Blow through the plastic tube to hear the water level switch click.
Inspect the plastic tube for a hole or pinched.
If these steps do not work replace the water level switch.

SOURCE: Whirlpool washing machine "lid switch" is broken

Found online:
Disconnect everything, power first. Keep the drain hose above the top of the washer if the bucket’s full of water. If there are clothes in it, remove them to a water-tight location (like a cooler or something).
Put the unit on an appliance dolly and get it onto the driveway before removing the drain hose from the rear of the unit. Water will gush out for a while here.
Unscrew the two hex bolts at the top of the unit that attach the plastic tabs to the console. Unscrew the screws in the end caps that attach it to the top of the cabinet. Unscrew the two hex bolts at the base of the rear panel that attach it to the base.
Pull the console forward and up a little to dislodge it. Slide it out of the way enough to get access to the two brass clips. Put a flat-head screwdriver in the hole towards the front and pry the clip forward a little to release it. Remove both clips. This releases the rear panel from the top of the cabinet.
One cable goes from the console to the top of the cabinet: this is the lid switch. Disconnect it.
Pull the cabinet forward now that everything is detached. It helps to have someone holding the console and rear panel while you do this. Remove the cabinet.
Place it on something to prevent scuffing, like a few towels or a small animal. The lid switch is the only device here. Unscrew it from the ground (one hex screw) and from the inside of the lid (two Phillips screws). Push the grey tube holding the wires out of the clip holding it in and release the plug from the top of the lid.
Take this to a parts shop and ask for another. It’s around $25-50 depending on how desperate you look.
Snap the gray tube back in, screw in the ground and switch. Close the lid: it should click now. If not, check that you actually screwed the new unit in properly. Yes, the new one.
Replace the cabinet and the rear panel, then the clips and the console. Replace all screws and bolts. Make sure there are no spare parts. Reattach all the cables and hoses and plug power in last.
Test it by putting it on a small load and let some water into the tub. Then stop it, move to spin dry, and start it with the lid open. Nothing should happen. Close the lid (you made sure to replace the drain hose, right?) and it should start spinning and pushing out water.
Congratulations, you saved over $100 and only lost a few hours of your life doing it.
And now you know where my morning went.
Pro tip: don’t let the lid fall down anymore. Place it down, don’t drop it.

Why is it displaying f2 code and will not drain?

The F2 fault code indicates a problem with the washer's drain system, and you must troubleshoot the problem to determine how to fix the washer and clear the code.
Clogged Drain Hose The drain hose on a Kenmore washer should remain free of obstructions so the water drains from the washtub. the drain hose behind the washer can impede the flow of water from the washer. A drain hose inserted more than 4 1/2 inches into a floor or wall standpipe drain system can cause the water to siphon back into the washtub.
Stuck Water-Level Pressure Switch Your Kenmore washer uses a water-level pressure switch in the control panel to detect the level of water inside the washtub. You can find the pressure switch behind the control panel in top-load models or attached to the inside wall of front-load models. The round switch is approximately 3 inches in diameter with a clear or black plastic tube connected to the bottom or side of the switch. The tube runs from the pressure switch to the exterior washtub. As the water fills the washtub, it changes the air pressure inside the tube and lets the switch know when the water has reached a predetermined level. A stuck contact on the pressure switch can stop the advancement of the wash cycle and keep the water from draining. A few taps on the top of the switch with a screwdriver handle can release the contact and fix the problem causing the F2 error code.

The plastic on/off panel that one presses (part of the plastic yellow top assembly of this model) is broken ... machine itself worx.

I can only suggest that you ,first post what your working on. Then post it to the right category. Even though car mechanics work on many different motors and such. I don't remember any black button on a yellow housing. Maybe John Deer tractors?

I have a karcher wv50 when i press the start button it just flashes

Roy it sounds like this is a problem. If it's flashing the pump may have stuck and you need to invest in a new machine. If its under any insurance make a claim.

How to install presure switch


The pressure switch is located behind the control panel. Its unction is determining the level of water in the washer.The switch looks like a round shaped plastic switch connected to wires and to a long thin rubber hose. To replace the switch disconnect power. Undo the screws holding the control assembly. Remove control assembly cover. Disconnect wires from switch and undo the screw holding the switch. Pull out the rubber hose from the tub and perform operations in reverse order to install the new part.

The switch is part nr.4 in diagram below. Click on the picture to enlarge:

Maytag neptune front load washing machine will not fully discharge water after the rinse cycle...HELP???

Check the drain hose and clear it from any debris that might be blocking the water from draining out completely. If the drain hose is clear of debris, check and clean the pump. Disconnect the machine from the power outlet before servicing for safety purposes.

Remove the rear access panel to access the pump and disconnect the wiring harness from the terminals of the drain pump and the pressure switch.

Loosen the clamps holding the drain hose and the tub hose to the pump assembly. It is a good idea to spread a towel under the pump before loosening the clamps.

Remove the hoses and rotate the pump assembly counterclockwise to release the pump assembly support legs from the keyed slot in the base of the washer. Remove the pump assembly from the washer.

Clear the pump impeller from any debris that might be causing it to work improperly. Clean the tub and the drain hose.

Reassemble the pump, the hoses, and reconnect the wires to the terminals of the pressure switch and the drain pump. Reinstall the rear access panel and run the machine.

Replace the pump (part #25001052) if water still do not drain out completely.

Remove the plastic bag covering the pressure switch. Press in the locking tabs on the back of the pressure switch and pivot the pressure switch off the pump bracket.

Grasp the pressure switch and lift the nipple of the pressure switch from the pump cap.

Install the pressure switch into the new pump assembly in reverse of the steps above.

My maytag washer leakes, all the water runs out on the floor.

Remove the rear access panel to check the source of the leak. The drain pump is most probably broken or the sump hose is damaged or detached from the tub.

Water will not stop filling the washer

I just fixed this problem on my GE washer that overflowed earlier into my hallway and living room. The fix required removing the tube from its connection at the outer tub and cleaning out some residue that was preventing air from moving to the sensor at the top of the machine at the control panel. No tools were needed other than a large steak knife to undo the clips to remove the front panel of the machine and a small flat head screw driver that I used to clean out the plastic pressure hose.

The good news is that even if this had not worked and the sensor/switch needed to be replaced, the part is available for replacement at the local hardware superstore and a few online outlets for around thirty dollars. Replacement of the switch looks to be relatively simple by disconnecting the existing wiring housing and replacing with a new part.

There are several detailed diagrams available online by doing a search for your product/ model number.

Be sure to check the hose before replacing the pressure sensor/switch- this will save time and money.

Good luck!
