I have just replaced the belt on my Creda Reversair Sensadry model 37650. I think this is similar to a number of Creda/Hotpoint models where you remove the front to replace the belt. You should be able to tell from the description below if this applies to your model. The steps below worked for me. Follow them at your own risk. Not the easiest repair, but a lot easier than I expected given descriptions elsewhere in this forum.
Replacement belt no 1700442 1894H7 purchased on eBay – often seems to be the easiest place to get spares these days.
Remove two screws from rear of top and slide back to remove
Prise off dial; remove two screws holding plastic panel in place; remove two wires from hi/lo heat switch; hammer three plastic lugs from rear to disengage from spring clips (may need to use punch on middle one to get access)
Lay machine on back to avoid stressing rear spindle when front is removed
Remove screws from narrow panel at bottom of front and remove panel
Remove three screws from top of front panel
Remove two screws holding timer control in place, and cable tie, to give more movement when panel is removed
Lift front panel away from drum carefully (wires still attached)
Remove two wires from sensor on ventilation duct at bottom left
The front panel should now be connected only by the wiring loom and there should be plenty of movement to allow you to clean inside the machine and fit the new belt over the drum.
Taking care not to damage the felt bearing, pay particular attention to cleaning fluff from around the drum seal to ensure easy refitting and avoid excessive friction.
Fit the belt over the drum ensuring grooved side inwards and no twists in the belt
Fit the belt over one of the tension rollers and the motor spindle – try to get it centred on the grooved part of the spindle rather than butted against the top lip. If you have trouble with this, you should be able to move it after fitting by turning the drum while applying gentle sideways pressure.
You should now be able to ease the belt over the second tension roller
Check that the drum turns and the belt is not twisted
Replace sensor wires
Refit front cover ensuring drum and vent pipe that goes from back to front are properly located
Replace all screws, bottom panel, timer control, top panel and control dial
Put machine back in upright position and switch on to check everything is working properly before refitting top panel.
