Hotpoint Washer Error Code EE: Main Board Memory Error... | appliancefaults.com

Technical Background:

The EE error code on a Hotpoint washer indicates a memory error within the main control board's microprocessor (MCU). This can be due to corrupted firmware, hardware failure within the memory chips, or interruptions in the voltage supply to the memory circuits. The MCU relies on stable voltage paths (typically 3.3V DC and 5V DC) to maintain memory integrity.

Symptoms:

The homeowner reports that the Hotpoint washer displays an "EE" error code on the control panel. The washer may not start, may stop mid-cycle, or may exhibit erratic behavior.

Possible Causes:

Main control board failure
Loose wiring harness connections
Voltage fluctuations or power surges
Corrupted firmware or software
Water damage to the control board
Incompatible replacement parts installed previously

Solution:

1

Disconnect the washer from the power supply by unplugging it or switching off the breaker.
2

Locate the main control board, typically behind the control panel or inside the machine's cabinet. You may need a 1/4-inch nut driver to remove screws.
3

Inspect the wiring harness connections to the main control board. Check for loose or corroded connections. Re-seat connectors to ensure a secure fit.
4

Use a multimeter to verify the power supply voltage at the control board is within the specified range (typically 120V AC). Check for voltage drops or fluctuations.
5

If the connections and voltage are good, suspect a faulty main control board. Replacement is usually required.
6

Obtain a replacement main control board that is compatible with the washer model number.
7

Install the new control board, carefully connecting all wiring harnesses. Ensure proper grounding.

Safety Warning:

Always disconnect the appliance from the power supply before performing any repairs. Lockout/Tagout (LOTO) procedures should be followed to prevent accidental energization. Be aware of high voltage circuits within the appliance.

Prevention:

Use a surge protector to protect the washer from voltage fluctuations. Avoid overloading the electrical circuit. Regularly inspect the wiring connections for signs of wear or corrosion. Periodically clean the washer to prevent water damage to the control board.

Expert Tip:

Some Hotpoint washers have a service mode that can be used to clear error codes. The specific sequence varies by model, but usually involves pressing a combination of buttons on the control panel in a specific order. Consult the service manual or search online for the correct sequence for your model.

Frequently Asked Questions

•How do I determine the correct replacement part number for the main control board?

The part number is typically printed on a sticker on the original control board. You can also find it by searching online using your washer's model number.

•What if the new control board doesn't fix the problem?

Double-check all wiring connections and voltage readings. There may be another underlying issue, such as a faulty motor or sensor, that is causing the error code. Consult a qualified technician.

•Is there a way to test the memory chips on the control board?

Testing memory chips requires specialized equipment and knowledge of electronics repair. It is generally more cost-effective to replace the entire control board if you suspect a memory issue.
