Hotpoint Washer Error Code F8: Water Supply Timeout... | appliancefaults.com

Technical Background:

The Main Control Unit (MCU) monitors the water level through the pressure switch. If the expected water level is not reached within a specific timeframe (the 'timeout'), the MCU will trigger an F8 error. The MCU sends 120V AC to the water inlet valve solenoids when it calls for water. A faulty pressure switch can also cause this if it is not signalling the correct water level back to the MCU.

Symptoms:

The homeowner reports the Hotpoint washer displays an F8 error code during the fill cycle. The washer may not fill with water at all, or it may fill very slowly.

Possible Causes:

Clogged inlet screens at the water inlet valve.
Kinked or blocked water supply hoses.
Defective water inlet valve (not opening fully or at all).
Low water pressure to the house.
Faulty pressure switch or hose.
Main Control Unit (MCU) failure.

Solution:

1

Turn off the water supply to the washer at the shut-off valves.
2

Disconnect the water supply hoses from the back of the washer.
3

Inspect the inlet screens on the water inlet valve for debris. Clean or replace if necessary.
4

Check the water supply hoses for kinks, bends, or blockages. Clear any obstructions.
5

Using a multimeter, test the water inlet valve solenoids for continuity. A reading of around 1k-2k ohms is typical. If open or shorted, replace the valve.
6

Verify the water pressure to the house is within the normal range (20-80 PSI). Use a water pressure gauge at an outside spigot.
7

Check the pressure switch and its hose for obstructions. If blocked, carefully remove the clog.

Safety Warning:

Always disconnect power to the washer at the breaker panel before performing any repairs. Use Lock-Out/Tag-Out (LOTO) procedures to prevent accidental energization. High voltage (120V AC) is present at the water inlet valve.

Prevention:

Regularly check and clean the inlet screens on the water inlet valve. Inspect the water supply hoses for kinks or damage annually. Check the house water pressure if you notice other fixtures are running slow.

Expert Tip:

On some Hotpoint models, you can enter service mode by pressing and holding the Start/Pause and Cycle Select buttons simultaneously for 3 seconds. This allows you to run diagnostic tests on individual components, including the water inlet valve.

Frequently Asked Questions

•How do I test the pressure switch to determine if it's faulty?

Disconnect the pressure switch from the machine and use a multimeter set to ohms. Blow into the pressure switch hose connection and check for continuity between the appropriate terminals. A change in continuity when you blow into the switch indicates it's likely functioning correctly, but it should be compared to the wiring diagram for specific readings.

•Where is the water inlet valve located on my Hotpoint washer?

The water inlet valve is typically located at the back of the washer, where the water supply hoses connect. You may need to remove the back panel of the washer to access it.

•If the water pressure is good and the inlet valve tests okay, could the control board still be the problem even without other error codes?

Yes, it's possible. While less common, a faulty control board can send incorrect signals or fail to properly energize the water inlet valve, even if the valve itself is functional. This would be a last resort diagnosis after confirming all other components are working correctly.
