WASHER
DISPLAY EXPLANATION AND RECOMMENDED PROCEDURE
F 34 LOAD DETECTED IN WASHER
DURING WASHER CLEANOUT CYCLE
The washer detects a load inside the washer tub
at the beginning of the Washer Cleanout Cycle.
Possible Causes
– Load inside the washer during the Washer
Cleanout Cycle.
– Friction between the drum and bellows material.
Procedure
1. Clear error code.
2. Unplug the washer or disconnect power.
3. Remove clothes from washer drum.
4. Verify that misalignment of the spin basket and the
T bearing on the boot is not causing friction (which
is interpreted by the motor as a load in the washer).
If bellows adjustment does not correct the friction issue,
the spin basket will need to be replaced.
F 70 COMMUNICATION FAILURE
BETWEEN CCU AND UI
Communication between Central Control Unit (CCU)
and User Interface (UI) has failed.
Possible Cause
– Electrical connection between CCU and UI
is damaged.
Procedure
1. Clear error code.
2. Unplug the washer or disconnect power.
3. Verify that the communication cable is connected
in the upper connector of the UI.
4. Verify continuity in the cable between the CCU
and the UIC.
If, after these procedures, the continuity test fails,
replace the communication cable. If F70 is still
present, replace the UI control.
F 73 UI FAILURE
F 74
Communication error within the User Interface.
Possible Causes
– A power surge/drop.
Procedure
1. Clear error code.
2. Unplug the washer or disconnect power.
3. Wait 2 minutes before reconnecting power.
4. Verify UI by attempting to start a cycle or run
diagnostic mode.
If these procedures do not correct the failure,
replace the UI control.

4. Check for broken coin sensor switch on coin drop.
5. Check the wire harness connections between User
Interface (AA4) and the coin sensor switch to ensure
wires do not block the coin switch beam.
6. Shorting the connections 2 and 3 at AA4 on UI will
simulate a good coin sensor.
If the above procedures do not solve the problem,
replace the UI.
d 9 LOW VOLTAGE DETECTION ERROR
Incoming voltage detected below 90 VAC for 8 seconds.
Possible Causes
– Voltage drop due to multiple washers
on same circuit.
– Worn outlet.
Procedure
1. Clear error code.
2. Unplug the washer or disconnect power.
3. Check the wire harness connection between the RFI
filter and the transformer.
If the above procedures do not solve the problem,
replace the UI.

The Coin 2 sensor is detected as blocked
for 8 seconds.
Possible Causes
– Coin vault full of money.
– Blocked or dirty sensor.
Procedure
1. Clear error code.
2. Unplug the washer or disconnect power.
3. Clean the coin sensor.
4. Check for blocked coin sensor switch on coin drop.
d13 only occurs with a coin 2 sensor installed. If the above
procedures do not solve the problem, replace the UI.
d 16 GENERATION 2 DEBIT CARD
READER ERROR
No communication from installed debit card reader
in Generation 2 debit mode for 5 minutes.
Possible Causes
– Card reader Gen 2 not installed, when washer

– Poor contact or communication cable not
connected between UI (AA3) and the card reader.
– Card reader failure.
Procedure

3. Check the wire harness connections between User
Interface (AA3) and the debit card reader Gen 2.
Do continuity test on cable.
4. Make sure you are using a Gen 2 card reader.
5. Reconnect power and wait for 5 minutes.
If the above procedures do not solve the problem,
replace the UI.
