Motor just hums. Does not wash or drain, but does a low pressure rinse cycle

Yes, a faulty water level pressure sensor can cause a washing machine to get stuck at the rinsing cycle and not drain. The water level pressure sensor is responsible for detecting the water level in the washing machine tub and signaling the control board to activate the drain pump to remove the water. If the pressure sensor is faulty and cannot detect the water level, it may not signal the control board to activate the drain pump, causing the washing machine to get stuck in the rinsing cycle.
To troubleshoot this issue, you can try the following steps:

1. Turn off the washing machine and unplug it from the power source.
2. Locate the water level pressure sensor, which is typically located on the side of the washing machine tub.
3. Check the wiring and connections to make sure they are secure and not damaged.
4. Use a multimeter to test the continuity of the water level pressure sensor. If the sensor is faulty, it will need to be replaced.
5. If the sensor appears to be working properly, check the drain pump and hoses for clogs or obstructions.
6. Reconnect the washing machine and run a cycle to see if the issue has been resolved.

If you are unsure about performing any of these steps or if the issue persists, it is recommended to contact a qualified technician for assistance.

indicates 2 possible faults
no agitation . spinning- indicates a problem start / run capacitor for the motor ( hum )
drain is a separate motor and will not run until drain is activated
and that comes back to the second possible fault
problem program board not progressing to wash cycle
the hum could be a water control solenoid
call a technician for a proper diagnosis

Is it SUE or SUD code?
Sud SUDS LOCK (Overdose of detergent detected during the wash cycle) The motor control unit senses a suds lock condition by analyzing the current draw on the drive motor. If "Sud" is displayed a potential suds lock is detected. This may signify a bad pump, an extra heavy load, excessive detergent, or excessive suds.

Potential Causes

• If too much detergent was used, run the unit through a Rinse/ Spin cycle then a Normal cycle without adding any detergent. This should clear the unit of the excess detergent.
• Check the drain hose and make sure it is not plugged or kinked
• Check Wire Harness connections to the Drain Pump, Pressure Switch, and Central Control Unit (CCU)
• Check / Clean Drain Pump Filter of foreign objects
• Check Drain Pump
• Check the Pressure Switch
• Check CCU

Check for power at the pump wires 120 volts when its in drain cycle.If voltage is good you need a pump. good luck thanks for voting

The humming sound is coming from the drive motor running but unable to drive the agitator nor the basket to spin. The drive motor is definitely running as the drain function works because of the fact that drain pump is directly coupled with the rear spline of the motor. The drain pump works in either direction as long as the motor runs. The problem is obviously a broken motor coupler which transfers the mechanical energy of the motor to the transmission. The solution then is to replace the broken coupler. Click on the link below for the detailed step-by-step procedure in replacing the motor coupler.

SUDS LOCK (Overdose of Detergent detected during the Wash Cycle)

The motor control unit senses a suds lock condition by analyzing the current draw on

the drive motor. If "Sud" is displayed a potential suds lock is detected. This may

signify a bad pump, an extra heavy load, excessive detergent, or excessive suds.

Humming could mean a stalled motor. These machines also have a coupling between motor and gearbox which can fail. However, the pump is attached to the motor, so if it's not pumping it probably means the motor isn't spinning. Check motor and/or gearbox.....Nomess

SUDS LOCK (OVERDOSE OF DETERGENT
DETECTED DURING THE WASH CYCLE)

The motor control unit senses a suds lock condition by analyzing the
current draw on the drive motor. If “Sud” is displayed a potential Suds
Lock is detected. This may signify a bad pump, an extra heavy load,
excessive detergent, or excessive suds.

Possible Causes / Procedure
■ If too much detergent was used:
—Run the unit through a Rinse/Spin cycle.
—Run a Normal cycle without adding any detergent.
This should clear the unit of the excess detergent.
1. Check the drain hose and make sure it is not plugged
or kinked.
2. Unplug washer or disconnect power.
3. Check wire harness connections to the drain pump,
pressure switch, and Central Control Unit (CCU).
4. Check/clean drain pump filter of foreign objects.
5. Plug in washer or reconnect power.
6. Check drain pump.
7. Check the pressure switch.
8. Verify CCU operation by running a Diagnostic test or any
cycle.

quite possibly the drain pump which would cause it to stick in rinse cycle. the humming noise you heard is probably the drain pump powered up but jammed. likely cause is a foreign object stuck in the pump impellor - main culprit is bits of bra wire. take the pump to pieces and extract whatever is jamming it.
