    when on the spin cycle it will run the drain pump for one minute and then stop. in other words it starts on 9:00 minutes runs the drain pump through 8:00 min. and then stops and shows 2:00 minutes on the timer, but will not ever spin or do anything else. does this help?

    While i wait - there are 3 possiblilities on why your washer will not spin.

    Defective Motor, Defective Speed Controller, Or defective timer.

    Any of these failing will cause the condition you are describing, and will need to be tested.

    BOSCH units are difficult to find parts for.

    Popping sounds usually indicate failed components on the controller board.

    With the correct model #, I can attempt to lead you to a part replacement.

    if you put it on a wash cycle, does it attempt to agitate once filled? Is there any clicking noise after the fill cycle indicating it is moving on to the next cycle - or does it stay silent? Same after the drain - is there any noise?

    The Nexxt series has a BIG (known) problem with the controller boards. They are prone to failure with minimal voltage spikes or current draws.

    It would be wise to test the 2 other components I listed earlier - as they are cheap in comparison to the board.

    If the board is the culprit - you're looking at around $300+ for the part.

    Testing is the key for your repair.

    If you're uncertain on how to test the motor, or speed controller - a service call might be in order for you. Once you open up the back of the machine - there should be a service manual inside that will let you know the spec tolerances for the speed controller and the motor.

    Throwing parts in without testing the old ones could get costly. A $80 service call would be worh determining if your $300 controller is bad... and then you'll have to weigh the option of using that $300 toward a new washer or fixing the one you have.

    A Digital Multimeter (and the ability to use it properly) is a requirement for testing your components.

    Sometimes simply opening up the machine will give you a better idea what is going on - sniff for burned electrical contacts and look for browned or black components. If there is no voltage to the motor during the spin cycle - the speed controller or the control board is bad (may be located on the same board on your unit).

    Decide which path you are going to take, and If you need more help, just let me know.

    one other thing that popped into my head after hitting send...

    your machine has a load balance sensor. if it has failed - it will not spin - as the controller does not get the required signal to start spinning (safety reasons)

    Thought Id offer that up as well....

    However - the machine not throwing out any error codes leads back to the controller board itself being at fault.

    the list is getting longer :D

    This will be the last comment until I hear back from you (i promise :) )

    If your door latch switch has failed - it is another safety mechanism that would stop any spinning action for safety reasons again... however it would throw out an error code too if it failed.

    Looking more and more like the Controller board, unfortunately.

    this could be your preliminary test. Simply jumper out the 2 wires going to the switch, and the washer will be tricked that it is engaged.

    Although it rarely helps, hav you unplugged the machine for 10 minutes to attempt a hard reset?

    Give it a try!

My washer is making a loud nosie when agitation starts

That is a normal sound when the transmission shifts from the last spin cycle to go into the agitate cycle. It should make a loud click sound that does not last longer than a second. There is nothing wrong with your washing machine.

Machine Starts filling then spins 3 turns and a loud noise and stops?

Hey friend, I appreciate your post!

From my understanding you Frigidaire washer will fill with water, spin three times, make a loud noise, and then stop. You could possibly be seeing an issue with your control panel or motor. I would recommend having a technician come out to the home to properly diagnose and repair your washer. I hope this is helpful. -Matt

Bosch SHU4312 won't finish cycle, won't drain.

The control board on these units is prone to a cold solder joint cracking. I have read that Bosch recommends replacement and will supply the board, not covering labor. I repaired mine prior and have done one for a friend as well. Has lasted several years and counting
The symptom is constant cycling without ticking down the last few minutes

Bosch Washing machine will not spin

Are you able to see the belt? Maybe it broke. If the drum is not spinning than sometime broke that would make the drum spin. If you machine is a direct drive then there is a problem with the drive shaft.

No water coming into machine. Programme not running because the machine is still trying to fill. If I add water the machine does drain. Was cleaned with a good dishwasher cleaner only last week. Nothing to...

Turns out that the dishwasher had a leak in the bottom. No water could be seen leaking out because Bosch machines have a cut-off valve that means if a tray in the bottom of the machine fills up with water, the float valve doesn't allow anymore water into the machine. we worked this out after we tipped the machine slightly, water ran out, when we put it back down and started it the inlet valve worked until the bottom had filled with water again.

New machine for us! However, not a critism of Bosch. We use our machine at least two or three times a day and have done for the last 5 years.

My dishwasher does not fill

suspect it has not drained fully hence will not fill. humming noise may be a foreign object stuck in the pump impellor. take pump out and check impellor turns freely
