Dishwasher not Drying Dishes

Specific failure symptoms include: 1) Dishwasher stops before the drying cycle. 2) The dishes are not dry when removed from the dishwasher.

When this problem is noticed, it is often not the fault of the dishwasher. The homeowner simply did not close the dishwasher door. A partially closed door will prevent the dishwasher from making electrical contact. When closing the door, make sure that the door shuts properly before starting the dishwasher.

Using Test Equipment

To avoid any incorrect readings when using the volt/ohmmeter always “zero” the ohmmeter scale (see your operating instructions) before making any continuity checks.

When making continuity checks with the volt/ohmmeter, always turn OFF the electricity at the circuit breaker panel. Live voltage checks made with the volt/ohmmeter in a continuity position will damage your volt/ohmmeter.

Check Dishwasher Plumbing

Check for stopped-up or backed-up house plumbing. Open dishwasher door and check to see if water is standing in the tub cavity. For additional information, refer to “Dishwasher Won’t Pump Out Water” section in this chapter.

Check Drive Motor Pump Assembly

To check the dishwasher pump assembly, it is necessary on most dishwashers to remove the drive motor and pump assembly from the dishwasher. Refer to Repair Procedures, “Dishwasher Won’t Pump Out Water” section in this chapter.

Check Timer Assembly

To check the timer assembly, refer to “Dishwasher Won’t Pump Out Water” section in this chapter.

Check Heater Element

Turn the electricity OFF at the circuit breaker panel. Remove the lower panel. Remove the wires that are attached to the heater terminals. Using the volt/ohmmeter, set the meter on the RX-1 scale. Connect one probe from the volt/ohmmeter, set the meter on the RX-1 scale. Connect one probe from the volt/ohmmeter to one terminal of the heater element. Attach the remaining probe to another terminal of the heater element. The scale of the volt/ohmmeter should show full scale deflection or 0 ohms. If you do not get a continuity reading, the heater element is defective — replace it.

REPAIR PROCEDURES

Turn the electricity OFF at the circuit breaker panelbefore attempting to service the dishwasher. Exercise care when removing the dishwasher from its space as the dishwasher legs can easily damage the floor.

To Replace the Dishwasher Plumbing

When major plumbing problems are suspected, it is recommended that a qualified plumber be called to make the repairs. The replacement of deteriorated plumbing requires knowledge, special tools, and welding equipment that are usually not available to the home repairman. For additional information, refer to “Dishwasher Won’t Pump Out Water” section in this chapter.

To Replace Heater Element

Turn OFF the electricity at the circuit breaker panel. Remove the dishwasher lower panel. Remove the harness wires attached to the heater element terminals. Remove the nozzle cap that secures the lower spray arm to the pump assembly. Remove the spray arm from the pump assemble. Remove the screws that secure heater element to the tub cavity and remove element.

Install the replacement heater element by mounting in the same place and position as the faulty heater element that was removed.
