My Whirlpool Imperial Series washing machine will not drain. It was recently moved from another home. Where and what should I start checking first.... ?

Here you go LSQ9549L

Hi there,
Well if it's a new machine then it look normal or let me know if you note some changes in natural function, most of this series washing machines shakes hard when they are on dry spinning. This series is mostly known for dryer's.

Make sure the drain hose is not sealed to the drain pipe, and that the hose is not shoved into the drain allowing the end of the hose to reach the trap. That will prevent the machine from syphoning out the rinse water as it fills.

CHANGE MOTOR COUPLING

replace the main (under tub) seal

as with basic spin faults -a number of reasons usually 1 motor brushes, 2 motor 3 motor control pcb or the obvious one - the belt has come off.

your washers drain hose is too far down the drain pipe which is causing a siphoning action pull the washers drain hose out pipe some you should be able to hear water dropping into the pipe the reason it only happens in the rinse cycle is because the water from wash is being drained and before the water vacuum is broken the rinse water comes in causing it to keep draining

it sounds like a worn clutch.

I had the same problem with this washer. It was the lid switch.
