Hotpoint Washer Lid Lock Bypass: Magnet Trick for... | appliancefaults.com

Technical Background:

The Main Control Unit (MCU) monitors the voltage signal from the lid lock switch. When the lid is closed and locked, the switch completes a circuit, signaling the MCU to allow the wash cycle to begin. The lid lock mechanism typically operates on 120V AC, engaging a solenoid to lock the lid.

Symptoms:

Homeowners report the washer not starting, displaying an error code related to the lid lock, or the lid failing to unlock after the wash cycle.

Possible Causes:

Faulty lid lock switch
Broken lid strike
Wiring harness damage to the lid lock assembly
Main control board failure
Obstruction preventing proper lid closure
Loose lid lock mounting screws

Solution:

1

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

Locate the lid lock assembly, typically on the washer top near the lid hinge. Use a 1/4-inch nut driver to remove any screws securing it.
3

Visually inspect the lid strike (the part that enters the lock) for damage or misalignment.
4

With the power OFF, use a multimeter to check the continuity of the lid lock switch. A closed lid should show continuity. Typically, you should see close to 0 ohms.
5

Check the wiring harness connected to the lid lock for any signs of damage, such as frayed wires or loose connections.
6

If bypassing with a magnet, understand this is for diagnostic purposes ONLY. A properly functioning lock is required for safe operation. A strong magnet placed near the lock sensor MAY simulate a closed lid. Measure voltage at the lock with a multimeter to ensure 120V AC is present during lock operation.
7

If the bypass allows the washer to start, replace the lid lock assembly. Order part number from parts supplier.

Safety Warning:

Always disconnect power to the washer before performing any repairs. Lock Out/Tag Out (LOTO) procedures are recommended. High voltage (120V AC) is present in the lid lock circuit. Exercise caution to avoid electrical shock.

Prevention:

• Avoid slamming the lid. Gentle closure prevents stress on the lid lock mechanism.
• Regularly inspect the lid strike for any signs of wear or damage.
• Ensure the washer is level to prevent excessive vibration, which can loosen connections.

Expert Tip:

Many Hotpoint washers have a service mode that allows you to run diagnostic tests, including testing the lid lock. Consult the service manual for the specific model to enter service mode. Often accomplished by pressing a sequence of buttons. This will show you error codes and let you actuate components individually.

Frequently Asked Questions

•What voltage should I expect to see at the lid lock connector when the washer is trying to lock?

You should typically see 120V AC at the lid lock connector when the washer is attempting to engage the lock.

•If the lid lock assembly tests good with a multimeter, what else could be the problem?

If the lid lock assembly tests good, the problem could be a faulty main control board, a wiring issue between the control board and the lid lock, or a misaligned lid strike.

•Where can I find the correct replacement lid lock assembly for my Hotpoint washer?

You can find the correct replacement lid lock assembly by searching online using your washer's model number at appliance parts retailers like AppliancePartsPros.com or RepairClinic.com.
