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

Technical Background:

The F97 error code on GE Monogram dishwashers typically indicates a problem with the heating circuit. The MCU monitors the current flow to the Calrod heating element. If the current is outside the expected range or no current is detected when heating is requested, the F97 error is triggered. Voltage from the MCU flows to the heating element through the high-limit thermostat.

Symptoms:

The dishwasher displays the F97 error code and does not heat the water. Dishes are not cleaned properly and remain wet after the cycle.

Possible Causes:

Faulty Calrod heating element
Open heating element circuit
Tripped high-limit thermostat
Malfunctioning main control board (MCU)
Wiring harness issues

Solution:

1

Disconnect power to the dishwasher at the breaker panel. Verify 0V AC at the dishwasher's junction box using a multimeter.
2

Locate the Calrod heating element at the bottom of the dishwasher tub. It's usually a U-shaped metal component.
3

Disconnect the wires connected to the Calrod element. Visually inspect for burns or corrosion.
4

Using a multimeter, measure the resistance across the Calrod element terminals. A reading of infinity (open circuit) indicates a failed element. A normal reading is typically between 10-25 ohms.
5

Check the high-limit thermostat (often located near the heating element) for continuity. If no continuity exists, the thermostat is tripped and needs replacement or reset (if resettable).
6

Inspect the wiring harness and connectors leading to the heating element and control board for damage or loose connections.
7

If the element and thermostat test good, suspect a faulty main control board (MCU). Replace the MCU.

Safety Warning:

Disconnect power to the dishwasher at the breaker panel before performing any repairs. Use Lock-Out/Tag-Out (LOTO) procedures to ensure the breaker remains off. High voltage is present in the dishwasher's electrical components.

Prevention:

Periodically run the dishwasher's self-clean cycle with a dishwasher cleaner to prevent mineral buildup on the heating element. Check for any leaks that may drip onto the element.

Expert Tip:

After replacing the heating element or MCU, perform a diagnostic cycle to confirm proper operation. On some Monogram models, this can be initiated by pressing and holding the 'Start' and 'Heated Dry' buttons simultaneously for 5 seconds.

Frequently Asked Questions

•What is the correct Calrod element part number for my GE Monogram dishwasher model?

You'll need to locate the model number of your dishwasher. It's usually located on a sticker inside the door or on the side of the dishwasher frame. Once you have the model number, you can search for the correct Calrod element part number online or at a local appliance parts supplier. Typical part numbers start with WB44.

•How do I test the high-limit thermostat?

With the power disconnected, locate the high-limit thermostat near the heating element. Disconnect the wires and use a multimeter set to continuity. A good thermostat will show continuity (a short circuit) at room temperature. If it shows no continuity (an open circuit), it's likely tripped or faulty.

•Where is the main control board (MCU) located and how difficult is it to replace?

The MCU is usually located behind the control panel on the dishwasher door or at the base of the unit. Replacing it generally involves removing the control panel or accessing it from underneath. Disconnect all wires from the old board, taking pictures for reference, and reconnect them to the new board in the same order. It can be a moderately difficult repair, so consider professional assistance if you're not comfortable with electrical work.
