GE Monogram Dishwasher F97 Error: Calrod Heating Element... | appliancefaults.com

Technical Background:

The F97 error code on a GE Monogram dishwasher indicates a problem with the heating circuit. The main control unit (MCU) monitors the temperature of the water via a thermistor and controls the heating element through a relay. If the MCU detects an abnormal temperature or an open/shorted circuit, it will trigger the F97 error code. The Calrod heating element is a resistance-based heater powered by 120V AC.

Symptoms:

The dishwasher displays an F97 error code. The water is not heating up during the wash cycle. Dishes are not drying properly. The dishwasher may stop mid-cycle.

Possible Causes:

Faulty Calrod heating element
Open heating element circuit
Defective heater relay on the control board
Wiring harness issue between the control board and heating element
Thermistor malfunction affecting heater operation
Grounded heating element

Solution:

1

Disconnect power to the dishwasher at the breaker panel.
2

Locate the Calrod heating element at the bottom of the dishwasher tub.
3

Disconnect the wires from the heating element terminals using a 1/4-inch nut driver.
4

Test the heating element for continuity using a multimeter. A reading of infinity indicates an open element. A reading of zero or very low ohms indicates a short to ground. Replace the heating element if defective.
5

Inspect the wiring harness and connections between the control board and heating element for any signs of damage or corrosion. Repair or replace as needed.
6

If the heating element tests good, check the heater relay on the control board for proper operation. A faulty relay may need replacement of the control board.
7

Reconnect all wires and restore power to the dishwasher. Run a test cycle to verify the repair.

Safety Warning:

Disconnect power to the dishwasher at the breaker panel before attempting any repairs. Use proper lockout/tagout (LOTO) procedures to prevent accidental energization. The heating element circuit operates at 120V AC, which can cause severe electric shock.

Prevention:

Regularly inspect the heating element for signs of damage or corrosion. Use a dishwasher cleaner monthly to prevent mineral buildup on the heating element. Avoid overloading the dishwasher, as this can strain the heating element.

Expert Tip:

To enter service mode on some GE Monogram dishwashers, press and hold the 'Start' and 'Heated Dry' buttons simultaneously for 5 seconds. This will allow you to run diagnostic tests and clear error codes.

Frequently Asked Questions

•What is the resistance reading I should expect from a good heating element?

A good heating element typically reads between 10 and 30 ohms. Refer to the appliance's tech sheet for the exact spec.

•How do I test the thermistor related to the heater circuit?

Use a multimeter to measure the resistance of the thermistor. The resistance should vary with temperature. Consult the service manual for the thermistor resistance chart at various temperatures.

•Where can I find a replacement Calrod heating element for my GE Monogram dishwasher?

You can purchase a replacement heating element from appliance parts retailers, both online and in brick-and-mortar stores. Be sure to have your dishwasher's model number handy to ensure you get the correct part.
