Amana Washing Machine Error Code F8E1: No Water Supply... | appliancefaults.com

Technical Background:

The MCU monitors the pressure sensor to determine the water level inside the washer tub. When the MCU commands the water inlet valves to open, it expects the pressure sensor to indicate a change in water level within a specified time. If no change is detected, the MCU triggers the F8E1 error code, indicating a no-water-detected condition. The MCU sends a 120V AC signal to the water inlet valves.

Symptoms:

The homeowner observes that the washing machine starts a cycle but no water enters the drum. The F8E1 error code appears on the display panel.

Possible Causes:

Clogged inlet screens on the water inlet valves.
Kinked or blocked water supply hoses.
Defective water inlet valve(s).
Low water pressure to the house (less than 20 PSI).
Faulty pressure sensor or wiring to the pressure sensor.
Malfunctioning MCU (Main Control Unit).

Solution:

1

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

Disconnect the water supply hoses from the back of the washer and inspect the inlet screens for debris. Clean or replace as needed.
3

Check the water supply hoses for kinks or blockages. Ensure proper water flow from the supply valves into a bucket. Water pressure should be at least 20 PSI. If low, contact your water company.
4

Using a multimeter, test the water inlet valves for continuity. A reading of approximately 1.3k ohms indicates a functioning valve. No continuity means the valve is defective and needs replacing.
5

Inspect the pressure sensor and its wiring harness. Check for loose connections or damaged wires. Using a multimeter, verify the voltage to the pressure sensor is approximately 5V DC.
6

If the issue persists, access the main control unit (MCU) and inspect for any visible signs of damage, such as burned components. If damage is evident, replace the MCU. Refer to the service manual for specific MCU replacement procedures.
7

After completing repairs, run a calibration cycle to ensure proper operation.

Safety Warning:

Always disconnect the power supply to the washing machine at the breaker panel before performing any repairs. Use Lock-Out/Tag-Out (LOTO) procedures to prevent accidental re-energizing of the circuit. High voltage is present inside the machine.

Prevention:

Periodically inspect and clean the inlet screens on the water supply hoses (every 6 months). Check the water supply hoses for kinks or damage annually. Ensure adequate water pressure is maintained to the home.

Expert Tip:

To enter service mode on most Amana washers, simultaneously press and hold the Start/Pause and Cycle Signal buttons for 3 seconds. This will allow you to run diagnostic tests and calibration cycles.

Frequently Asked Questions

•What is the proper procedure to test the pressure sensor on this Amana washing machine?

Disconnect the pressure sensor. Use a multimeter to measure the resistance while slowly applying air pressure to the sensor. The resistance should change proportionally to the applied pressure. Consult the service manual for specific resistance values at different pressure levels.

•How do I determine if the main control unit (MCU) is faulty, and is there a way to test it?

Visual inspection for burned components is a primary indicator. You can also use a multimeter to check for proper voltage outputs from the MCU to the water inlet valves when they are supposed to be energized. However, confirming MCU failure often requires component substitution (replacing the MCU with a known good one).

•Where can I find the service manual for my Amana washing machine model?

Service manuals can often be found online through appliance parts retailers or dedicated service manual websites. Make sure to have the exact model number of your washing machine when searching.
