GE Profile Dry Boost Dishwasher Beeping and Stopping:... | appliancefaults.com

Technical Background:

The dishwasher's Main Control Unit (MCU) monitors various sensors and components. If the MCU detects an error, such as a stuck float switch, a faulty door latch, or overheating, it will trigger an audible alarm (beeping) and halt the wash cycle. Voltage paths from sensors provide feedback to the MCU.

Symptoms:

The GE Profile Dry Boost dishwasher beeps multiple times mid-cycle and then stops. The wash cycle does not complete, and dishes are not properly cleaned.

Possible Causes:

Float switch malfunction
Faulty door latch
Overheating issue
Circulation pump failure
Control board problem
Clogged drain pump

Solution:

1

Turn off the dishwasher's breaker at the breaker panel. Verify power is off with a non-contact voltage tester.
2

Open the dishwasher and check the float switch located at the bottom of the tub. Remove any debris that may be obstructing its movement. The float should move freely. If damaged, replace it.
3

Inspect the door latch assembly. Use a multimeter to check the continuity of the door switch when the door is closed. It should read close to 0 ohms. If not, replace the door latch.
4

Remove and clean the filter assembly at the bottom of the tub. Inspect the drain pump for clogs. Clear any obstructions.
5

Test the circulation pump motor windings with a multimeter. Resistance readings should be within the range specified in the service manual. A typical reading might be 10-20 ohms. If the winding are open or shorted, replace the pump.
6

Check the thermistor. It should read approximately 50k ohms at room temperature (70-75 Fahrenheit). Replace if out of spec.
7

If the problem persists, the control board (MCU) may be faulty and need replacement.

Safety Warning:

Always disconnect power to the dishwasher at the breaker panel before attempting any repairs. Lockout/Tagout (LOTO) procedures should be followed. The appliance operates on 120V AC, which is potentially lethal.

Prevention:

Regularly clean the filter assembly and check for debris in the drain pump. Avoid overloading the dishwasher to ensure proper circulation.

Expert Tip:

Enter service mode by pressing and holding the Start/Reset and Heated Dry buttons simultaneously for 5 seconds. This will display any stored error codes. Consult the service manual for code definitions and troubleshooting steps.
