Dishwasher will not empty after cycle and motor makes humming noise hotpoint dishwasher bf1260

No a noise filter is a different kettle of fish. That stops electrical interference noise from affecting your television, radios and electrical devices.

The most likely source of the hum is the start capacitor on the motor, or the motor itself.

This has a different idea

Humming or Grinding If your Samsung dishwasher makes noise when starting that sounds like a low hum, it's part of normal function. The motor makes this sound as it operates throughout the wash cycle. However, a dishwasher making loud humming noise or grinding sounds could mean that debris is caught in the drain pump.

This says the drain pump, but the drain pump only runs to empty out so it wouldn't do it all the time.

No model and brand name .
the way you mention look like the main motor jammed and making the humming noise click out on overload then the humming noise stop and after a while it will humming again and continue like that until you switch off the machine. If the dishwasher is old I would recommand you buy a new one instead of changing the motor.
God Bless have a nice day Dickson

empty out the unit and recheck the arm and rack then start it up empty and check operation --if huming but working properly --stated it does drain so motor is operating ---then its operating normal ---if arm still not working will need to remove arm and check gear or shaft for damage

Both problems sound like motor has failed or is failing.

It sounds like the pump motor has failed but the timer is working to turn on the heating element.
Recommend you replace the motor.

dear sir the problem you have sounds like the solenoid that opens the drain actuater can be worn out open the bottom panel run tru a cycle observe when the solenoid open it may be that there is something causing the solenoid to buzz either worn out or a wire or something in the way causing not to close proprly thanks from gilles

motor turns to cast the water around the dishes.that motor shaft is in close by a water seal.it must have gone bad allowed water on to the motor bearings which would be your noise.could be bad.open your bottem panel turn on unit and watch whats happening.when you see that decide what parts you will need ,check cost and think if thats what you want to do.God bless,tom

your wash motor is jambed or the motor capacitor is faulty

humming is the motor powered up but not turning. burning smell is the motor overheating. cause may be the motor capacitor which is a cheap part. try replecing it and hope thge motor survived. could also be a foreign object in the pump impellor
