I just replaced the water pump. When I turned it on to run an express cycle all the machine would do was to run water out of the drain. It would not start the wash cycle or fill the tub. It seemed like it was stuck in the drain cycle. I need help on this to figure it out.
Answer Hello Tim,
Raise the main top and feel of the inside of the front panel. The tech sheet should be located there in a zip lock bag. Try not to rip the bag so it will not get wet, (it should always be kept in this location so it can be found if service is necessary in the future). This sheet will fully explain how to run the self-diagnostics so you can see if any fault codes have been set. This is where technicians are trained to start. Once you pull the fault codes, follow the tech sheet to locate the issue with the unit.
How do I tell if this is the OPR switch or the FLD switch? What if I need both?
Answer Hello Dan. Here are the instructions from the manufacture. Hope this helps.
The washer uses two pressure switches to control the amount of water entering the tub and to protect
against an overfill condition. The operating pressure switch, marked OPR, controls the amount of
water that enters the tub during normal wash and rinse functions. This switch operates in the same
manner as similar pressure switches through a pressure switch tube, diaphragm and switch. The
switch contact is normally closed and will open on pressure rise.
The overfill pressure switch, marked FLD, is used to guard against failure of the operating pressure
switch or an overfill condition caused by the consumer adding water to the basket. The overfill pressure
switch operates in the same manner as the operating pressure switch, except it’s trip setting is
slightly higher than the operating pressure switch. The switch contact is normally closed and will open
on pressure rise. These pressure switches are NOT interchangeable.
If an overfill condition is detected, the overfill switch will signal the electronic control which causes it to
discontinue the current cycle. “FL” will flash on the control panel display and the beeper will repeat a
warning every 10 seconds. The pump is cycled in drain mode for a half minute on, half minute off until
the overfill switch is reset or power is disconnected from the washer. If the flood switch does reset, the
washer will remain in standby mode with “FL” displayed. It will not automatically restart the cycle.
Operating and Over Fill Pressure Switch Test
Check the hose connections between each pressure switch in the console and the pressure dome
attached to the tub.
If hose connections are good, check the Operating Pressure Switch as follows:
• Press HEAVY DUTY then START to start a cycle. Let the unit fill and see if the operating
pressure switch turns off the water.
• Check the voltage across Pins P and V of the operating pressure switch. If 12VDC is present,
the water level switch has opened the switch.
• If no voltage is present and the water has filled the tub to a visible level (above the nutate
plate), stop the cycle and replace the operating pressure switch.
If hose connections are good and the Operating Pressure Switch is good, check the Overfill
Pressure Switch as follows- NOTE - PERFORM THE FOLLOWING STEPS IN THIS ORDER:
• Pull the hose off the Operating Pressure Switch so that the washer can fill beyond the operating
switch trip point.
• Press HEAVY DUTY then START to start a cycle. Let the unit fill and see if the overfill pressure
switch will trip.
• Check the voltage across pins P and V of the overfill pressure switch. If 120VAC is present,
the water level has opened the switch. This should also shut off the water inlet valves and give
an FL indication on the 7-segment display.
• If no voltage is present and the water has filled the tub to an overfill level, stop the cycle and
replace the overfill pressure switch. Drain out the water by starting an EXTEND SPIN
cycle. Do not allow the wash plate to nutate under water.
