AQ113F497IUK Drum issue
Hi.
I have a <2year old Hot[oint AQ113F497IUK which I have been very happy with. Wife loves it for the 11kg load, with three teenagers.
However it recently started knocking when spinning, noisier when slow. I greased the bearing at the back, no change.
I tried reducing the washing load weight and using a lower spin speed, no difference.
Last week, big bang, emptied water, but no drum movement but I could here motor spinning.
Took inspection cover off back, Drum pully in half, on bearing, belt (unbroken) and half a pulley in bottom of machine.
Drum and motor spin well by hand, no horrible noises from either. Believe knocking was probably due to the drum pulley gradually going out of shape and catching on back of drum?
Problem is I'm having trouble removing the Drum Pulley bolt. Its a star TorX but I'm not sure of the size. I've tried T20 which appears too small and a T30 is way too big.
I believe the pulley and screw are Loctited in so they will need heating up with a heat-gun to break this. Believe its a standard anti-clockwise thread to undo?
Any advice on the bolts removal and it's TorX size would be much appreciated.
Thanx.
Regards,
Rob.

Hotpoint AQ113F497IUK broken drum pulley with bolt removal query
- The problem
- The washing machine developed knocking during spin, then failed with a loud bang. It drained but the drum would not turn, although the motor could be heard spinning. On inspection, the drum pulley was found broken in two, with part still on the shaft and part in the bottom of the machine. The belt was still intact.
- Likely cause
- Confirmed fault was a failed drum pulley. The earlier knocking was probably related to the pulley deforming or loosening, but that explanation was not confirmed in the discussion.
- What fixed it
- The accepted advice was that the pulley bolt may possibly be a left-hand thread, though this was not confirmed. It was also advised that these bolts are commonly secured with Loctite or another locking method, but a heat gun should not normally be necessary. Care was advised because shearing the bolt could cause major problems. The exact repair was not confirmed.
- Checks to try
- Machine emptied water but drum did not move while motor could be heard spinning
- Rear inspection cover removed
- Drum pulley found split in half
- Drive belt found unbroken
- Drum and motor both turned by hand without obvious bad noises
- Parts or tools mentioned
- drum pulley
- pulley bolt
- drive belt
- Torx driver
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

It could be a left-hand thread but not sure. They are usually either Loctited in or have some tab or mechanism to prevent them coming loose. You shouldn't normally need a heat gun. Loctite is usually fairly easily broken. If you sheer the bolt you could have major problems so be careful.
