I have a MW511, it doesn't drain it just makes a humming noise

Sounds like a wheel bearing .

Have the wheel bearings been checked?

See if you can spin the drum with little resistance or is it really hard to spin?

Hello leah_mcmunn - the error code E-20 indicates that the water doesn't drain. This could be caused by either the drain hose is kinked or your household drain is clogged. If the drain pump is making a humming noise, check the restriction in the drain line. If not, then you might need to contact a professional to possibly replace the pump.

Fault code 66 is pressure sensor is faulty
66. (01000001) Pressure Transducer Error [Ptx Frequency > 90 kHz]
Note: this supersedes Fault code 65 from V41 Motor controller code onwards.
The Motor Control module has received signals from the water level sensor (Ptx)
above normal frequency values.
Primary Source: Motor Control module
Action: Replace Motor Control module

The humming is probably your image stabilizer, and may be normal. Try turning it off in your camera's menus to see if that improves battery life. If it does, you may need to consider higher power lithium batteries if you wish to continue use of the image stabilization feature.

hi the fault may be down to the brushes on the motor

Your Dial may be bad.

Hi,

• Get the washer laying on it's side and using the access hole on the bottom carefully remove the screw clamp holding the large hole of the rubber housing to the tub drain (it will be obvious all other clips are green compression clips).

• Carefully work the strainer out of this flexible rubber drain housing through the large hole.Clean it out and replace you will be good to go. Also remove all the hoses and check for a buildup of gunk. Hope this will fix your problem.

Thank you !!
