Troubleshooting
The Probe Malfunctioned: If the probe connections are found good, disconnect the probe
and measure the resistance between the leads. The resistance between the leads should be
between 2K and 35K Ohms. The resistance between either lead and the ground should be
infinite.
Level Still Made — The water level in the cylinder is at or above the configured low water lev-
el at the start of the formula, before the first bath step. The controller issues an error but the drain
remains open. If a slow drain caused the error, the error clears when the transducer senses that the
water level in the cylinder is less than the configured low water level.
Drain Blocked: Do a check that the drain valve and drain outlet are clear of debris.
Transducer Tube Blocked: The tube from the shell to the pressure transducer may be
blocked. Check the tube and remove lint or other obstructions.
Drain Valve Malfunctioned: The drain valve or drain valve solenoid may have malfunc-
tioned. Electrical troubleshooting is required.
Serial Communication Failure — A peripheral board in the control box has lost communica-
tion with the processor board. The controller stops cylinder rotation and waits for serial commu-
nication to resume. This error dialog box closes when serial communication resumes.
Board Failure: A peripheral board in the control box cannot communicate with the pro-
cessor board. Electrical troubleshooting is required.
Failed Speed Sensor — The controller cannot verify that the cylinder is turning. If the speed
sensor fails at extract speed, the machine cancels the extract sequence and coasts for the default
coast time. The default coast time must expire before the door will unlock.
Speed Sensor Failure: The cylinder speed sensor has stopped working. Electrical trouble-
shooting is required.
Inverter Tripped — The inverter that controls the motor had an error. The controller turns off
all outputs, cancels the wash formula, and returns to the Home display.
Inverter error: The machine controller cannot tell about the specific error. See the inverter
manual for details. The inverter manual was shipped in an electric box on your machine or
with the packet of documentation inside the machine cylinder.
