Dry Heater Thermistor Error - Out
of Range Low
Check that the thermistor harness is plugged in. Check
that the terminals are not bent inside the connector
housing.
F60 Heater Relay Stuck on Fault
Clear faults and cycle power to unit. If fault reoccurs
within 60 seconds of power up, replace MC board.
F61 CSM Check Failed
Cycle power and start cycle to clear fault. If fault does
not clear, replace main control.
F62 Dry Heater Fan Error
Check dry heater fan operation and verify speed is
greater than 2,500 RPM. Check that the dry heater fan
harness is plugged in.
F63 Flood Condition Fault
The pressure sensor has detected the water level
above the ood limit. Check the water valve for a stuck
open valve (continuous ll into the tub). Run the Fill
Test under the Diagnostics Test tab and ensure the
pressure sensor is in the range of 40.77 and 40.44 Hz.
Check that the ll funnel or door vent conduit at the
bottom of the door is not obstructed or blocked. This
can cause a pressure build up in the tub as the unit
heats during a cycle.

F112 Key Stuck
Pushbutton Models: Check button operation, each
button should “click”. Check for plastic ash. Replace
user interface (UI) board.

inadvertent button contact, controls in Delay Start or
Control Lock mode, and consumer education. Check
that each key operates, each button should "beep"
and light up once pressed. If a key doesn't respond,
replace user interface (UI).
