Indesit tumble dryer only gets warm

SOURCE: Defy Tumble dryer not heating

Is this an electric dryer? If so, the most common problem would be a burned-out heating element. There could also be a defective temperature sensor inside. This will need to be evaluated by a qualified appliance repair technician to find the exact cause.

SOURCE: how to fit a belt on a tumble dryer

unplug the dryer,
220v is not fun
dryers are generic inside, regardless of maker
while you got it apart to replace the belt is a good time to clean out exhaust vent pipes and the squirrel cage fan, no lint, better air flow, less $$ to run
the tensioner may push Up on the lower run.

• open case, most front panels are removed including door, remember to disconnect door switch wires, set panel aside
• pull drum out
• check drum support rollers
• check drum felts, bushes guides
• locate tensioner pulley, belts have been known to pull them out of the mounting when it breaks, check , reinstall if out
• pick up broken belt off floor of case
• take belt to parts store and match it, despite the huge number of dryer models there are very few belts.
• If any felts or rollers are worn,stuck,damaged take them too to the parts store, and replace in pairs, despite the huge number of dryer models there are very few rollers or felts
• after ensuring rollers anf felts and bearings are serviceable, loop new belt around drum at the wear mark from prior installation, reinsert drum
• loop new belt around motor pulley.
• pull tensioner pulley against spring to end of motion
• loop belt around tensioner pulley
• allow tensioner to slowly move back by spring tension till the belt is taut

SOURCE: indesit condenser tumble dryer water

Maybe trapped water in the dryer. Switch off and remove power from wall. Remove condenser unit from the dryer (clean the condenser while you have the chance with plenty of water and an old toothbrush - it will probably be filthy). With the condenser unit removed stick an old tea towel in the hole where the condenser was and then tip the dryer on its side. If there is water it will either run onto the tea towel or onto your kitchen floor OR into the water container!

It worked for me, honest...

SOURCE: Tumble dryer trips electricity

I own the same machine and this happened to me, if the internal working of the machine get wet it will cut off causing the electrics to trip. This model is a condenser dryer, at the bottom of the machine if you open up the flap you will see the condenser on the left hand side, the manufacturer recommends that you clean this unit once every month and also empty the reservoir and clean the fluff filter after every use. While this may seem like a lot of hard work there is a very good reason for this. I suspect that your problem is due to a build up of fluff and or gunge in the condenser and bottom of the machine. Remove the condenser and give it a good clean of all fluff, you can run water through it either in the sink or bath as the best way to do this it is very fiddley using just your hands. Next check to see if there is a build up of water in the back the machine where the condenser usually sits, you will have to lie on your stomach and reach into the back of the machine (OBVIOUSLY ENSURE THAT YOU HAVE UNPLUGGED FROM THE MAINS SUPPLY BEFORE YOU DO THIS!) along the floor of the machine you will feel a channel cut into the plastic which runs into the sump at the back of the machine, if you have not cleaned the machine properly this is probably blocked and is the culprit. With this blocked the water is unable to travel to the pump that takes the water from the condenser into the resevoir at the top of the machine, and therefore it stays in the machine and can get thrown about onto the electrics and could cause the machine to cut out and trip your electrics! If this is not blocked check the black rubber pipe leading from the pump to the reservoir is not blocked, failing that perhaps the pump (in the plastic case at the back of the machine) is faulty and will need to be replaced. If water has built up in the machine you will also need to check to make sure none is sitting in the heater coil compartment (it did with mine) to get at this you will have to unscrew the metal plate at the back of the machine and let any water out. Leave the machine for a few hours to make sure it is dry and then give it another go. If your machine is still under warranty though i would call indesit first as they may get a little funny if you remove any of the machine covers yourself and refuse to look at your machine.
