Monogram Professional Washer: Troubleshooting 5 Beeps at... | appliancefaults.com

Technical Background:

The Main Control Unit (MCU) monitors the drain pump circuit for proper operation. It sends a 120V AC signal to the drain pump and expects to see feedback indicating that the pump is running and draining water. The pressure switch provides feedback to the MCU that the water level is decreasing. If the MCU doesn't receive the expected signals, it triggers the 5-beep error code.

Symptoms:

The Monogram licensed technician washer completes the wash cycle but beeps 5 times at the end instead of proceeding to the final spin or signaling cycle completion. The clothes may be excessively wet. The homeowner reports the error consistently occurs after the drain phase.

Possible Causes:

Drain pump failure or obstruction
Pressure switch malfunction
Main Control Unit (MCU) error
Wiring harness damage to the drain pump circuit
Clogged drain line

Solution:

1

Unplug the washer from the power outlet.
2

Check the drain hose for kinks or obstructions. Disconnect the hose and flush it out with water.
3

Access the drain pump (usually at the bottom front of the washer, behind an access panel). Use a 1/4-inch nut driver to remove the panel.
4

Inspect the drain pump for foreign objects. Remove any debris.
5

Use a multimeter to test the drain pump for continuity. If there is no continuity, replace the drain pump. Verify 120V AC is present at the pump connector during the drain cycle.
6

Check the pressure switch for proper operation. A faulty pressure switch can cause this error.
7

Reassemble the washer and plug it back in. Run a test cycle to see if the error is resolved.

Safety Warning:

Disconnect power to the appliance before performing any repairs. Use proper Lock-Out/Tag-Out (LOTO) procedures to ensure the appliance cannot be accidentally powered on during service. High voltage is present in the control panel and drain pump circuit.

Prevention:

Periodically check the drain hose for kinks and obstructions. Avoid overloading the washer with excessive laundry, which can strain the drain pump. Run a washer cleaning cycle with a washing machine cleaner every month.

Expert Tip:

Some Monogram washers have a service mode. Consult the service manual for instructions on how to enter service mode and run diagnostic tests. This can help pinpoint the source of the error more accurately. It also helps to check the voltage to the drain pump. If voltage is present, but the pump is not running, this confirms pump failure.

Frequently Asked Questions

•Where is the pressure switch located on this Monogram washer?

The pressure switch is typically located at the top of the washer cabinet, connected to a small hose that runs to the bottom of the tub. It's usually accessible after removing the top panel of the washer.

•How do I test the pressure switch?

You can use a multimeter to check the continuity of the pressure switch. Disconnect the power and the wires to the switch. Use an ohmmeter to check continuity in both the empty and full states. Refer to the service manual for the correct resistance values.

•What is the part number for the drain pump on this specific model?

The part number for the drain pump can vary depending on the specific sub-model. Check the model number on the washer and then consult the parts list on the Monogram website or contact a parts supplier. Provide them with the complete model number to get the correct part.
