Hotpoint Washer Splashing Water During Fill:... | appliancefaults.com

Technical Background:

The washer's Main Control Unit (MCU) controls the water fill cycle. The MCU sends 120V AC to the water inlet valve to open it. The pressure switch monitors the water level and sends a signal (usually a change in resistance or voltage) back to the MCU when the correct level is reached. The MCU then de-energizes the water inlet valve, stopping the fill cycle. A faulty pressure switch, hose, or valve can cause overfilling.

Symptoms:

The Hotpoint washing machine is filling with too much water during the fill cycle, causing water to splash over the top of the tub.

Possible Causes:

Faulty water inlet valve continuously allowing water to enter the tub.
Defective pressure switch failing to signal the MCU to stop the fill cycle.
Clogged or kinked pressure hose preventing accurate water level detection.
Malfunctioning MCU not properly interpreting the pressure switch signal.
Siphon effect caused by drain hose issues.

Solution:

1

Disconnect power to the washer at the breaker panel. Verify 0V AC at the wall outlet.
2

Locate the water inlet valve. Visually inspect for cracks or damage.
3

Disconnect the water supply hoses and check for debris. Clean as needed.
4

Use a multimeter to test the water inlet valve solenoid for continuity. A reading of around 1.3k ohms is typical; an open or shorted reading indicates a faulty valve.
5

Locate the pressure switch and pressure hose. Ensure the hose is securely connected and free from kinks or clogs.
6

Replace the water inlet valve if the solenoid is faulty.
7

If the issue persists, replace the pressure switch. Reconnect power and observe the fill cycle.

Safety Warning:

Always disconnect power to the washing machine before performing any repairs. Lockout/Tagout (LOTO) procedures should be followed to prevent accidental re-energization. Voltages present in the machine are lethal.

Prevention:

Periodically inspect the water supply hoses and pressure hose for leaks, kinks, or clogs. Clean the water inlet valve screens annually to prevent debris buildup. Run a washer cleaner cycle monthly to prevent soap residue buildup that can affect pressure switch operation.

Expert Tip:

Many Hotpoint washers have a calibration mode that can be accessed through a specific button sequence (refer to service manual). Running this mode can sometimes resolve minor level sensing issues.

Frequently Asked Questions

•How do I locate the pressure switch on my Hotpoint washer?

The pressure switch is typically located near the bottom of the washer, often behind the front panel. It's a small, round component with a hose connected to it. Refer to the washer's service manual for the exact location.

•What is the correct ohm reading for the water inlet valve solenoid?

The correct ohm reading for a Hotpoint water inlet valve solenoid is generally around 1.3k ohms. However, this can vary slightly depending on the specific model. Consult the service manual for the exact specification.

•Could a faulty drain pump cause overfilling?

While a faulty drain pump doesn't directly cause overfilling, if the drain hose is improperly installed or the drain pump is weak, it can create a siphon effect, pulling water into the tub even after the fill cycle has stopped. Ensure the drain hose is properly elevated and the drain pump is functioning correctly.
