    There is no problem with the belt which is tight and in good condition.. The outer drum rotates well and smoothly- it is the inner chrome drum which is loose and is knocking against the outer drum.How can the inner drum be tightened?

    I have had no reply to my comment that it is not the fan belt which is loose. It is the inner chrome drum which is loose inside the outer drum which is stable. How can I tighten the inner drum?

    Yes- you are correct about the problem.

    I cannot see your schematic.

    The front of the machine clearly states it is an AWM 1866- the model number on the warranty card (warranty expired) is 857086615030.

    We live in UK where it was bought.

    Thanks for help.

So the inner drum your saying is knocking around on the inside of the outter drum? First thing to check would be the seal and bearing then this is what connects the two tubs together another questions for you im trying to look up your model on whirlpool canada and this is the closest they are giving me to that model number please check this schematic to assure that this is your unit because im am not finding that model when trying to look up the schematic for your machine are you located in NZ or another area sometimes you have to know the area to find which whirlpool has the schematics to your machine I await your reply Thanks Rick

If the belt has come off, then there will be a lot less resistance than usual when turning the drum. The best person to test this is the one that usually empties the drum of clothes when it's finished a wash. They are used to the resistance on the drum as they turn it to check for items of clothing stuck to the drum. The best method though is with the washing machine unplugged and the back panel removed to see if the belt has come off or not.

If the belt has come off, then there are usually reasons for this. It's rare for a belt to come off for no reason although it can happen. Clearly if it comes off again after being refitted, there is likely to be a fault. Here are some possible causes of a washing machine belt coming off:-

*The drum pulley is loose.

*The drum bearings have gone (collapsed) causing the drum pulley to wobble.

*The drive belt was to slack.

*A motor fixing bolt or bracket securing the motor to the tub has broken or come loose.

*Water has got onto the belt causing slippage.

*An obstruction or item of clothing temporarily jammed the drum causing the belt to spin off.

However there is a question how tight should a drive belt be on a washing machine?

The answer is it has to be fairly tight. You should be able to pluck the belt and get a nice resounding "ping". The belt shouldn't be over tightened though. Roughly speaking there should be some sideways play, you should be able to move the belt from side to side approximately a quarter of an inch.

Check the bellow instructions:-

Unplug the power cord before beginning any work. Pull out the washing machine out and create enough work space behind the machine.

Remove the back panel of the machine by unscrewing the 6-10 screws and setting them aside. Lift the panel off the washing machine.

Locate the drive belt and check for damage. If it is cracked or broken, it will need to be replaced. If it has slipped off, it will need to be reattached. Determine if the drive belt is tight by pulling on it. If the belt does not snap right back, it is loose.

To tighten the belt, loosen the nut that mounts the motor and push the entire motor forward to increase the tension on the belt. Hold the motor in place and tighten the nut. If the drive belt is damaged or cracked, remove it.

To replace the belt, unscrew the clamps that secure the pump coupling--a rubber flexible part connecting the motor to the drum/tub. Remove the clamps and take the belt off. Slide the new belt on and screw the clamps back into place to secure the pump coupling.

Model WM-14316FD. Why is drum out of alignment and making a knocking noise when it washes and spins?

You need to open the machine and check that the bolt in the center of the tub/motor is tight, tighten if loose.
Other possible cause is the tub bearings.

My beko washing machine was making a racket like this. What it was was the large blocks of concrete bolted to the drum had come loose. Solution was to get a 13mm socket with a bar and extension and tighten them up really hard as far as I could manage. THen the probelm dissapeared no more banging. Worth a try if your has similar blocks attached to outer drum
