Hotpoint Dishwasher Flashing Start Light: Reset Guide &... | appliancefaults.com

Technical Background:

The flashing Start light usually indicates an error code or malfunction detected by the dishwasher's Main Control Unit (MCU). The MCU monitors various sensors and components, and if a fault is detected, it signals the user through the flashing light. The voltage paths related to the door switch, float switch, water inlet valve, and drain pump are critical for proper operation. Disruptions in these voltage paths can trigger the error.

Symptoms:

The homeowner reports that the Start light on their Hotpoint dishwasher is flashing continuously, and the dishwasher won't start a cycle. They may have tried pressing the Start button repeatedly without success.

Possible Causes:

Door switch malfunction.
Control board failure.
Wiring harness issue.
Float switch stuck in the up position.
Water inlet valve malfunction.
Clogged drain pump or filter.

Solution:

1

Disconnect power to the dishwasher at the breaker panel.
2

Check the door switch using a multimeter for continuity when the door is closed. A reading of approximately 0 ohms indicates continuity. If open, replace the door switch.
3

Inspect the wiring harness, especially near the door hinge, for any signs of damage, corrosion, or loose connections. Repair or replace as needed. Use wire strippers, crimpers, and electrical tape for repairs.
4

Examine the float switch in the dishwasher tub. Ensure it moves freely and is not stuck in the up position. Clean any debris blocking its movement. Use a wet/dry vacuum to remove standing water.
5

Test the water inlet valve with a multimeter for proper resistance (typically around 500-1500 ohms). Measure across the terminals. If open or shorted, replace the water inlet valve. You may need a 5/16-inch nut driver.
6

Inspect the drain pump for obstructions. Remove the lower access panel (usually with a 1/4-inch nut driver) and check for clogs in the drain pump housing. Clear any blockages.
7

If all components check out, suspect a control board failure. Replace the control board, ensuring the new board is properly configured for your model. The board is usually behind the control panel, accessible after removing a few screws.

Safety Warning:

Always disconnect power to the appliance at the breaker panel before performing any repairs. Dishwashers operate on 120V AC, which can cause serious injury or death. Use proper Lock-Out/Tag-Out (LOTO) procedures to prevent accidental power restoration.

Prevention:

Regularly clean the dishwasher filter to prevent clogs. Avoid overloading the dishwasher, which can strain the motor and other components. Periodically run a dishwasher cleaner to remove mineral buildup and maintain optimal performance.

Expert Tip:

Many Hotpoint dishwashers have a service mode that can display error codes. To enter service mode, press and hold the Start button for 5 seconds, then press the Heated Dry button three times within 6 seconds. The error code will be displayed through the indicator lights.

Frequently Asked Questions

•How do I access the control board on my Hotpoint dishwasher?

Typically, you'll need to remove the outer door panel by unscrewing the fasteners around the perimeter. Then, carefully detach the control panel assembly. The control board is usually mounted behind the control panel.

•What is the typical lifespan of a Hotpoint dishwasher control board?

A control board's lifespan can vary, but it generally lasts between 5-10 years. Factors like usage frequency, power surges, and environmental conditions can affect its longevity.

•How do I know if the replacement control board needs programming?

Some replacement boards are plug-and-play, while others require programming to match your specific model. Check the manufacturer's instructions that come with the new control board. If programming is needed, you may need specialized tools or a qualified technician.
