POTENTIAL CAUSES

dishwasher pauses 2 or 3 times during
the cycle for thermal holds and advances
once temperature is met.
OWI soil sensor picking high soil cycle
too often.
Diverter problem prevents water from
heating efficiently.
A water heating problem can cause long
cycles, but will typically also cause a
water heating fault code.
Heater takes a long time to heat water
with low voltage.
Incoming water under 84°F (29°C)
Suds or air in pump requires repeated
wash periods.
OWI or NTC temperature sensor
problem.
Motor problems force cycle to start and
stop repeatedly.
Control is programmed to stop cycle and
alert customer when certain fault codes
have been detected.
