cycle too often.
1. Run Service Diagnostics cycle to check if OWI
is showing high soil with no soil added.

3. Replace OWI.
NOTE: If OWI soil sensor is replaced, run
Diagnostics after installing new OWI to force
calibration on next regular wash cycle.
Heater takes a long time to heat
water with low voltage.
Check for at least 100 VAC at power source.
A water heating problem could
cause long cycles but will
typically cause a “water heating
fault”.
