Admiral Washer Error Code Sud: Troubleshooting Excess... | appliancefaults.com

Technical Background:

The washer's MCU (Main Control Unit) monitors the water level and drain pump activity. The pressure switch provides feedback to the MCU about the water level. If the MCU detects unusually high water levels or slow draining combined with high suds, it triggers the 'Sud' error. Voltage paths from the pressure switch and drain pump feedback to the MCU are critical for proper operation.

Symptoms:

The Admiral washer displays the error code 'Sud' during the wash cycle or rinse cycle. The washer may stop mid-cycle and not proceed. You might see excessive suds inside the washer drum.

Possible Causes:

Excessive detergent usage.
Incorrect type of detergent (not HE).
Drain line blockage causing slow draining.
Faulty pressure switch (measures water level).
Defective water inlet valve allowing overfilling.
Malfunctioning control board (MCU).

Solution:

1

Unplug the washer from the 120V AC outlet.
2

Check the drain hose for kinks or obstructions. Remove any clogs.
3

Locate the pressure switch and inspect its hose for blockages. Clear any debris. Use a multimeter to check continuity of the pressure switch.
4

Examine the water inlet valve for proper closing. If it continues to drip when the washer is off, it needs replacement. Use a multimeter to check the valve solenoid (should read around 1k-2k ohms).
5

Reduce the amount of detergent used in future loads. Always use HE (High Efficiency) detergent.
6

Clear the drain pump filter. Usually located behind a small access panel on the front of the washer. Use a 1/4-inch nut driver to remove the access panel.
7

After addressing the above, run a clean washer cycle with no detergent to clear any remaining suds.

Safety Warning:

Disconnect power to the washer at the breaker panel before performing any repairs. Capacitors can hold a charge even when unplugged. Exercise caution around electrical components. Lock Out/Tag Out (LOTO) procedures should be followed.

Prevention:

Use only HE detergent and measure the recommended amount according to the detergent packaging. Regularly check the drain hose for kinks. Clean the drain pump filter every 3 months.

Expert Tip:

To access the service mode on some Admiral washers, press and hold the 'Start/Pause' and 'Power' buttons simultaneously for 5 seconds. This may allow you to run diagnostic tests and clear error codes. Refer to the service manual for your specific model.

Frequently Asked Questions

•How do I know if my pressure switch is bad?

A faulty pressure switch can provide incorrect water level readings to the control board. Use a multimeter to check its continuity. Also, inspect the hose connected to it for any blockages or leaks. If the hose is clear and the switch has no continuity or incorrect resistance readings, it's likely defective.

•What is HE detergent and why is it important?

HE stands for High Efficiency. HE detergents are formulated to produce fewer suds, which is essential for high-efficiency washers that use less water. Using non-HE detergent can cause excessive suds, leading to the 'Sud' error and potential damage to the washer's components.

•Where is the drain pump filter located on my Admiral washer?

The drain pump filter is typically located behind a small access panel on the lower front of the washer. You may need a flathead screwdriver or a 1/4-inch nut driver to remove the access panel. Be prepared for some water to spill out when you remove the filter, so have a towel handy.
