Hotpoint wd420 leaking

Depends on which clip is fitted, if it's the metal type with loops on the ends then you squeeze the 2 together with pliers or mole grips but if it's the plastic type they are like teeth inside and you have to push the middle section outfrom the outer in opposite directions. Can be done with a flat blade screwdriver but be careful of you fingers.

Remove the lower rear panel of washer, locate and remove the large black hose fastened to bottom of drum.
Remove and clean plastic filter inside the hose.

Yes, there is a filter.
Remove back panel, remove large black hose fastened to bottom of drum, and remove and clean filter inside the hose.

Check your pump is ok and filter not any blockage as this is common cause/ Fiter located within sump hose...bottom of drum take clip off to remove.

There is no adjustment provided for tensioning belt as it is a stretch belt.
Best way to do it is to remove the rear panel, tilt the weaher forwards, get someone to hold it for you.
Put belt round motor pulley first, then slowiy feed it round the drum pulley, turning the drum pulley at the same time, it will be very tight, so watch your fingers, just keep going until belt is on, if it comes off, just start over
You can line it up properly in the motor pulley grooves once you have got the belt on.
Please rate my solution.
Thankyou.

If you cannot here it catching, then leave well alone, if it is still catching, then you could to try to locate it by removing the lower rear cover of washer, remove the large black hose on bottom of drum, and see if you can locate it from the bottom of the drum.
Hope this helps.

You nead to check the filter.

Unplug at the mains, remove lid and door catch can be released from inside the machine.

if the drum is tight to turn ,then the main bearings have probably seized, or their could be something fast in the drum. Remove belt, and try to turn the drum by hand , it shuold be free with no resitance.
If it is noisy or feels rough, then the bearings have gone.

Did who ever install this machine make sure that it was installed correctly and draining properly. The burning smell will go away with time.
