Important Tips for GE Models

GE dishwashers with Water Temp Boost/Wash Heat Boost extend wash time to raise temp, but rely on functional internal heating components and adequate hot water supply

Possible Causes

Insufficient water heating (low incoming water temperature or failure of internal heating system)

How to Identify: Dishes come out greasy/cold, water inside dishwasher feels cool mid-cycle or after cycle; Water Temp Boost cycle does not noticeably raise temp above ~120°F as intended; check hot water supply temperature at sink.

Part: Heating element, thermostat, high-limit thermostat

Detergent dispenser not opening due to obstruction, mechanical failure or dispenser component damage

How to Identify: Detergent or pod remains in compartment after cycle, dispenser door doesn’t open fully, visible residue/clogs around dispenser.

Part: Detergent dispenser lid/latch/spring
