Wiring diagram Hotpoint 31331 tumble dryer Door lock

SOURCE: Replacing the Drive Belt

I am not an expert but I do have a Hotpoint 9334 Tumble Dryer which I guess is similar to the 9314.
To replace belt or heater element you must remove the front panel complete with door.
Screws are different sizes in different places so note where they belong as you remove them.

1. Remove 2 screws at rear top which go through the brackets holding the top panel, slide back the top panel a little and lift it off.
2. Pull off the rotary timer knob and remove 2 screws beneath.
3. This is the tricky bit! Remove the the plastic panel which covers the switches etc.. This panel has 5 plastic fingers which secure it to the metal plate behind, locate the ends of the fingers where they pass through the metal plate. Using a metal rod or punch and a hammer, tap the ends of the fingers to push them back through the holes easing each in turn a little at a time to avoid distorting the plastic unduly. (This is a bit scary as you have to hit them quite hard and the fingers look fragile)
4. Open the door and remove the 4 screws then remove 3 screws at the top and 3 screws at the bottom of the front panel. Lift and ease forward the front panel, unhook the door catch release wire, pull off the electrical connectors and put the front panel aside.
5. Lay the machine on its back and remove 1 screw holding the element housing to the top plate and pull off the electrical connectors.
6. Fit the belt around the drum, through the idler pulleys and over the motor spindle.
7. Put it all back together.

Hi, - The first thing to do is UNPLUG THE DRYER! Then remove the heater cover situated on the back panel. It is the curvey shaped panel.
Remove all the screws and the panel may be slightly stuck - just prise it off.

Next - there are 2 small screws holding the heater and thermostats assy onto the back panel. - Remove these to free the assy from the back panel. Be careful not to touch the elements as they break easily.

The problem is probably the Thermostats.

The one on the left is the Overheat Thermostat - You will notice a small hole in the centre of the thermostat. Take a Pin and push it firmly into the hole and you may hear the Stat "click". That has re-set the stat.
Re-assemble the Dryer being careful with the elements.

Now - Why has it tripped? If it has overheated it is because of one or all of the following.

1. The Condenser unit is getting blocked - Remove and clean under running water like a hosepipe or tap.
2. The door filter is not being cleaned
3. Sometimes opening the door to check if the clothes are dry and then not allowing the dryer to cool down can cause the problem. Always allow it to go through the cool down process.

Hope this helps. The Heater and the Thermostats are available as Spares - Terry
