The pressure switch or sensor is actuated by the water pressure when flowing like in a camper. only much higher settings. it should be on the pump housingthere should be a couple wires going to a box which cuts the motor on and off.

"PE" error is related to the Harmonic pressure switch. Since the
part is electronic, I would suspect a clog at the air dome at the
bottom of the tub located at the rear of the machine. The pressure
switch is located at the top. Unplug the washer from power, you will need a small piece of 1/4" plastic tubing or copper tubing. Locate
the pressure switch, disconnect the 1/4" tube from PS. Attach the
PS hose to your plastic or copper extension tube. Try and blow thu.
You should hear bubbling of air. Draw alittle water in by sucking and
blowing several times. This should clear any thing lodged in the lower
air dome. Before you reattach the hose to pressure switch, first trim
1/4 '" of hose off, for a tight fit. But before attaching hose, plug in washer and Press POWER, Press SPIN SPEED, Press START
to activate pump to remove all the water left in the tub. Next lower the
Pump's Trap Door at the bottom left corner of the cabinet. Using a kitchen trash bag, Extend the black rubber hose into trash bag and remove the plug. Turn off the machine when all water has been
evacuated.. Unplug washer and reattach the hose to the pressure
switch and try again.. IF error returns replace Pressure Switch..
This advice is for Kenmore Elite and Whirlpool Duet model FRONT LOADERS displaying the “FH” error code. "F/H" indicates that either you have no water coming into the washer, or very little water.
If you have NO water coming into the wash tub after 30 seconds the error code is displayed.Check the following:
- Inlet water valve may be clogged. Clean inlet screens if necessary. - Make sure water taps are on. - Check inlet hoses for kinks or clogs.
If you HAVE water filling the wash tub, and after 8 minutes, 10.5 gallons of water has been detected by the flowmeter, but there has not been a detected a Pressure Switch trip, the inlet valves are turned off and the error code is displayed.Check the following:
To access the Drain Pump - UNPLUG the washer and take the lower panel under the door off by removing the three screws under the bottom edge. HINT: Propping the front feet of the washer up can make access much easier. I use a couple small blocks of wood. With the screws removed, the panel should drop down then come off. If it sticks, tap either side and it should come free.The pump is located directly under the wash tub in the front of the washer.Verify the electrical connections are good and that the pump is running.If not, click on the following link to check the pump for obstructions: http://www.fixya.com/support/r385845-checking_drain_pump_in_whirlpool_duet To access the Flowmeter and Pressure Switch – remove the three screws in the top panel along the back of the washer.With the screws removed, the panel should slide back, then, lift off.The flowmeter will be located on the left-hand side of the washer (facing from the front) between the inlet valve and dispenser.It’s a small white plastic device with hoses attached.The pressure switch is located on the right-hand side of the washer in the rear.It is a round plastic device with electrical connections and a hose attached. There should be a tech sheet directly behind the panel or attached to one of the interior cabinet walls.Please refer to this sheet to learn how to perform diagnostics, how to locate the components mentioned, and the specific measurements required determining if the components are good or bad.
I hope this helpful. Please post back if you can't find the tech sheet and/or need further assistance.
If the washing machine won't fill up, make sure that the water supply valves are turned on. Next, make sure there are no kinks in the supply hoses that run from the supply valves to the washing machine. If nothing is obstructing the hoses, you may have another controls issue.
Several of the washing machine controls are also responsible for the washing machine not draining, continuing to fill or filling too slowly. If the washer doesn't want to drain or stop filling, the issue could be the pressure switch. When water enters the machine, water also fills a tube in the pressure switch. When the air pressure reaches a certain point, it triggers a switch that will stop the machine from filling. Locate this pressure switch on your machine and look for damage. If you have a multimeter, use it to find any electrical issues. If there is no reading, the pressure switch needs to be replaced.
Hope this will help u..............Verify Flow meter operation and that the Pressure Switch hoses are intact and connected properly. Remove the three screws in the top panel along the back of the washer. With the screws removed, the panel should slide back, then, lift off. The flowmeter will be located on the left-hand side of the washer (facing from the front) between the inlet valve and dispenser. It's a small white plastic device with hoses attached. The pressure switch is located on the right-hand side of the washer in the rear. It is a round plastic device with electrical connections and a hose attached. There should be a tech sheet directly behind the panel or attached to one of the interior cabinet walls. Please refer to this sheet to learn how to perform diagnostics, how to locate the components mentioned, and the specific measurements required in determining if the components are good or bad.
If the drain time exceeds 8 minutes the water valves turn off. After 4 minutes the “Sd” error will be displayed, then 4 minutes later the F21 error code will be displayed.
Press PAUSE/CANCEL two times to clear.
1. Check the drain hose and make sure it is not plugged or kinked. 2. Unplug washer or disconnect power. 3. Check the electrical connections at the pump and make sure the pump is running. 4. Check the drain pump filter for foreign objects. 5. Plug in washer or reconnect power. 5. If the above does not correct the problem, go to step 7. 6. Unplug washer or disconnect power. 7. Replace the pump.
Alternative Procedure: If the machine cannot be forced to its diagnostic mode then:
1.Disconnect the washer from the power supply and water supply. 2.Remove the top panel by taking out the three screws in the back of the washer. The pressure switch is right on top. 3.Remove the Molex connector from the water level switch / pressure switch. Refer to the picture below. 4.Reconnect the power supply but not the water supply. 5.Power the machine. The machine will enter diagnostic mode. 6.Power off the machine. 7.Replace the water level switch / pressure switch. 8.Reconnect the water supply. 9. Power on the machine it will work without error
There is a pressure switch to cut the motor once target pressure is reached. I.e. when the nozzle is closed. It's a black cheap plastic thing, right in front of the pump body. It has a white plastic lever to trip the switch. It was sticking intermittently on mine. the simoniz 1600 is quite a cheap peace of ****, needs fiddling around every time I use it
try running the machine without the hose attached if the machine runs ok then it is probable the there is a blockage in the nozzle if the the machine still cuts out then the pressure switch will probably be stuck or faulty this switch will be inline with the on/off switch and the motor it can be checked using a multi meter after dissconecting the power.
