New tumble dryer - thermal trip

Crombers01

Hi all. Hoping someone can enlighten me on the possible issue I am experiencing.

We have a brand new tumble dryer (condensing) that is housed externally within a storage unit. The dryer itself has plenty of air circulation around the unit as the doors remain or will atleast remain open whilst in use. The dryer has tripped the thermal cut out on the extension lead being used to draw power. The extension lead is a good quality brand and is 6 months old.
The machine will operate for 20mins and thereafter trip the thermal cut out...
Can anyone shed some light on the potential issue here?

Thanks in advance.

You shouldn't be using an extension lead to run the tumble dryer. It's cutting out because it's not rated for the appliance, and it's preventing a more serious issue from happening.

Get an appropriately rated socket installed for it and stop using the extension lead. If you can't do that inside the storage unit, then set up the tumble dryer inside the house, but again don't use an extension lead.

Is the extension lead big enough for a tumble dryer? It needs to be 13 Amp.
Is the extension on a reel? It needs to be unwound.

The tumble dryer may draw up to 13 amps and many extension leads are only rated at 10 amps or less.

What is the power consumption of the dryer?

What is the power rating of the extension lead?

How long is the extension lead?

What is the distance between the tumble dryer and the nearest electrical socket?

Can you install a spur from that socket to a point close to the dryer? That would be better than using an extension lead.

Robust, heavy duty 13A cable reel with 4 x sockets. Only one socket is being utilised to supply the TD.

Cable has not been fully unwound so will try that. The new dryer is replacing an old unit which was housed and supplied in the same manner without any issues. Distance from dryer to the nearest socket on the ring is approx 4m. I would need to install a new external socket point and butcher the unit to allow the TD to be plugged in direct.
4.79Kwh - Energy consumption full load

4.79 kW is 20.8 Amps at 230V - surely that's not the peak electrical demand, otherwise a standard 13A plug wouldn't be enough anyway. kWh is time dependent so not the peak instantaneous load.

What is the peak unit rating in kW? Or the model reference for the tumble dryer?

I am at work at the moment so don't have all load information to hand, only quoting something from an online data sheet for the product. Model is Indesit IDC8T3B.

I have submitted an enquiry to determine the price for an electrician to come round and take a dedicated supply off the ring to the unit. Safety first.

A little surprised I hadn't encountered this problem with the last dryer though which was of a similar capacity.

That's kWh not kW. It's 2700W which is near enough 13 Amps.

that

the doubting thomas in me says it is not 4.79kw.

The element is 2300W, another 2.47 kw for a motor, fan, pump and some electronics - doubful. I agree with essexexile that it will be more around 2700w

You do know the older version of this were a fire risk? Best keep it in the garage.

Did you actually read the rest of my post?? kWh is time dependent, so there is no way that you can equate 4.79 kWh to 2700W...

Yup, I read it.
