5.2 Diagnosing

(troubleshooting)

Washer test programs diagnose issues so well that diagnosis and resistance measurements usually aren’t needed. Troubleshooting information is
attached below if needed.

Symptom

Problem

Solution

Washer won’t start.

Electricity is disconnected
or has been turned off.

Cycle selector knob or
control module has failed.

Make sure washer is connected to an appropriate 120V, 60 Hz
circuit (according to local codes). Turn on electricity.

Control module has onboard cycle selector knob. Check
voltage output to water inlet valves and drum motor (when
they’re energized). If no voltage, replace faulty control module.

Washer won’t fill.

Water supply turned off.

Water inlet hose filters
(strainers) blocked.

Water pressure too low.

Control module has
failed.

Water inlet valve(s) has
failed.

AQUA

STOP

®

hose has

tripped.

Turn on water supply.

Check water inlet hose filters. Clean if dirty. Replace filters if
damaged.

Check incoming water pressure.

Check voltage output to water inlet valves (when they’re
energized). If no voltage, replace faulty control module.

Measure resistance of water inlet valves (~ 2.7 – 4.5 k

Ω

).

Replace inlet valve(s), if faulty.

If

AQUA

STOP

®

hose indicator is

red

, replace hose.

Washer won’t drain.

Drain pump or pump
motor protector has
failed.

Control module has
failed.

Disconnect drain pump and measure resistance at connector
(~ 140 – 200

Ω

). Replace drain pump if faulty.

Check voltage output to drain pump when it’s energized. If no
voltage, replace faulty control module.

Washer overheats.

Control module has
failed.

NTC failed.

Check voltage to heater. If voltage is present when heater
shouldn’t be on, replace faulty control module.

Disconnect NTC and measure resistance at terminals (~ 22.8 –
27.4 k

Ω

@ 20ºC (68ºF)). Replace NTC if faulty.
