Question about Whirlpool duet Washing Machines
There is no such error code on this unit. This could be F/H code for not having water go into machine. May you check your water source is coming through both as hot and cold water, do they were reversed, do you hear any humming noise from the back at the unit. Do the following steps to check.
Press PAUSE/CANCEL twice to clear the display.
1. Make sure that both valves at the water source(s) are turned on all the way.
2. Check for plugged or kinked inlet hoses or plugged screens in the inlet valves
3. Verify inlet valve operation
1. Verify Drain pump operation
2. Pressure Switch Hose is in good condition and properly connected to Tub and Pressure switch

I have read many posts for this problem and I have my own solution. I interface computers to real world aplications and when I saw the control board for this washer I was appalled at what I saw. The tiny relays on that control board are rated for 10 or 16 amps. These are fine if you are only driving small devices but they cannot take the startup currents and back EMF of solenoids and motors. I have tried filing the contacts and resoldering edge connectors all to fail to solve the problem. So, I replaced 2 relays involved in the most critical operations. One was the small relay (K4) that activates the door lock/unlock solenoids. BUT instead of simply replacing the relay, I rewired the harness and added an industrial relay to do the heavy work of actuating the solenoids. I also replaced the main relay (K6). This relay is what the entire machine uses for all motors, solenoids and other relays depend on to operate. Here again, I diverted where the power goes to. The power that normally passes through K6 is now just used to operate an industrial rated relay.
I used original relays for the control board due to the fact that the electronics on that board were intended to only operate tiny relays. I simply diverted the power to drive larger relays. This was no easy task and it is not to be performed by anyone other than an expert in this field. I have a number of photographs and I am willing to share them with anyone who wishes to see what I did.
I would bet that very few of these control boards have actuall gone bad. Only the relay contacts have been slightly scorched to the point of intermittent reliability.

My machine had the F21 code and the inlet to the pump was blocked with change, bobby pins, small rocks, pieces of fuzz and clothing. Removed the front cover of the mahine and removed the cap on the front side of the pump and cleaned this trap area out. The pump motor quit humming and the machine worked like it is supposed to!

Error code F70 means no communication is detected from the Central Control Unit (CCU) to the User Interface while F71 is the reverse; no communication detected from the User Interface to the Central Control Unit (CCU). This could simply mean a loose or poor connection between the two communicating boards.
Disconnect power to the washer prior to servicing to avoid the risk of electric shock.
Remove the three screws attaching the top panel to the rear of the washer then slide the panel rearward and lift it off the washer.
Disconnect the User Interface ribbon connector from the left side of the Central Control Unit (CCU) and clean the connector and terminals thoroughly. Reseat the connector several times to ensure a good connection between the Central Control Unit (CCU) and the User Interface.
It is highly recommended to clean and reseat every wiring harness connector from the Central Control Unit (CCU) to prevent the same problem in the near future.
Reconnect every wiring harness to the CCU and make sure all connectors are firmly seated. Slide the top panel back into position and secure it to the rear of the washer with the screws previously removed.
Let us know if the problem persists for further assistance. We will be happy to resolve your problem.
