Power to Front Control Panel

The body control system consists of the following 3 modules:
• The Dash Integration Module (DIM)
• The Instrument Panel Module (IPM)
• The Rear Integration Module (RIM)
Each of the 3 body control modules integrate a number of functional systems under the control of a single module. Each module is connected to the Class 2 serial data circuit, many of the control functions are implemented by Class 2 messages.

Check the heater coil for opens or shorts.

Did you have a power outage recently? They are notorious for damaging circuit boards--usually about 3-4 weeks after the power interruption strange things will either start happening or *not* happening with appliances due to damaged computer chips on the boards starting to fail. Your symptoms indicate either a blown user interface(push button panel) or a defective main control board(board with the brains on it) or both!

Check the buttons on the control panel using a volt/ohm meter. In most cases, the control panel must be replaced. If that doesn't solve the problem, the electronic control board might be at fault.

It could still be a plug or wire problem but if not a power problem inside the machine or a printed circuit board or other internal failure. It will not be possible to diagnose the problem without a lot more inforamtion.

The error code E41 means the control board is detecting an open door switch. It might be due to a broken wire harness, broken door lock/switch assembly, or in worst cases a faulty control board.

Unplug the machine or disconnect power. Open the washer door then look for the retaining hoop securing the door seal around the lip of the door opening. Stretch the spring of the retaining hoop then remove it.



Carefully peel off the part of the door seal from the lip of the door opening near the door lock/switch assembly. Remove enough of the door seal to gain access to the door lock and switch assembly.



Remove the screws securing the door lock/switch assembly to the front panel. Once the screws are removed, lift the door lock and switch assembly then pull it away from the front panel.



Take the door lock/switch assembly out of the front panel then disconnect the door switch harness then short circuit the terminals by putting a jumper wire between them.



Put the door lock/switch assembly back into position in the front panel then secure it with the securing screws previously removed. Properly put the eased part of the door seal back over the lip of the door opening then secure it with the retaining hoop. Reconnect power and run a test cycle. Replace the door lock and switch assembly (part #131763202) to address the problem if the washer works fine with the door switch bypassed. If not, replace the control board.

Hi,

E1 and F1 error code indicates a faulty ERC board. Disconnect power to the range (unplug the range power cord or turn the power off to the range at the circuit breaker). It is very important that the power to the range has been disconnected, so please double check before continuing. Gain access inside the control panel.Disconnect the touch pad (also called keypad or membrane switch) ribbon from the ERC. Make sure there are no lose wires, or anything else that may cause a short when power is turned back on. Assemble the control panel back the way it was.Turn the power back on. Wait for an hour to see if the code comes back (usually accompanied by a beeping sound). If code comes back, replace the ERC. If it does not, replace the touch pad.

Thank you !!

These control boards do not have fuses on them. I opened mine up when the front panel touch pad stopped working and the LED indicators were anemic. This is a sign of the ribbon cable connections have oxidized. The ribbon cable connects the touch pad to the control board.
Others have written up nice solutions on similar Maytag diswashers with the touch pad.

The previous expert shows that you can diagnose this by using a 10k resistor and connecting pin 6 and 10 on the ribbon cable connector and it will start the dishwasher (you have to trip the door handle and carefully do this with the power on). This proves that the control board is fine and ribbon cable connections are the problem. Don't forget to quickly trip the door latch once the dishwasher starts.

My solution was to purchase a contact cleaner called Deoxit. You can order from RadioShack.com or get at Frys. Spray Deoxit on both the ribbon cable end (removed) and into the connector on the control board. Deoxit removed the oxide on the connectors. The twin pack Deoxit spray comes with a solution that helps prevent corrosion. I am 1 day into the successful repair of this model Maytag dishwasher.

Previous people have suggested heat and steam get into the control board and oxidize this connector. I notice on the top right where the control board sits, there is a gap to allow steam to get into the door/control board area. I used bathroom caulk to seal both sides of the door to hopefully prevent further corrosion.

Sounds like the control panel may be dead. If you cannot get any lights to come on at all on the front panel, its probably a goner. You can check the voltage coming out of the control pc board via the schematic inside the dryer panel. I have this same exact problem. I replaced the control board 3 times because the panel seems fine if i plug it into an external power supply but will not work when plugged into my dryer. I have my jumpered and running off of a circuit breaker.

The booster heat control circuit is controlled by the relay board. Visually check for loose or burnt relay contacts...
You will see the booster LED light when it calls for heat. Some newer machines have a second high limit on the right hand side of the booster tank.
It may be your control board is configured for low temp with no booster. When you power up, the display should say LX30H. If not
Pull open the upper drawer, place a magnet over the door interlock switch.

CAUTION, 220 volt power is present. be carefull what you touch.

on control board, short J5-1 and J5-2, then power up. You are in factory setup. press select on the control board to see each option on the front panel., press up arrow on control board to step up through options for each step. when done, press the off button on front panel. remove short and start up normally. With the magnet in place, AND THE DOOR CLOSED, run the machine and observe the relay board status lights.
If you want to adjust the temp set points, with the machine off, press and hold the hidden key behind the front panel logo, and press select on the control board.. Or on power up, hold the wask key..Same to adjust options as above. Press off to exit.
