Hotpoint CTD40 tumble dryer

This m/c works for a short time then the on/off led light starts flashing and counting from top to bottom the led lights on the left – (2,3 &4) start flashing too. The m/c keeps turning but no heat.

I can’t find any reference in Known fault codes – can anyone shed any light? the two toc’s at the rear read ok 🙁

Should have gone to Specsavers 😆

CTD 80/85 codes

There is only one TOC, the other is an NTC. 😉

F07 Lower element failure
Check security of module connector J4;
Test between pins 4 and 3 on J4 (approximately 48 Ohms);
If open circuit, test lower element and wiring between J4 and
the heater.
70802.0000, from this serial the one shot thermostat is wired into module if this operates the unit will appear dead

Definately two tocs, but didn’t see the ntc squeezed between them- which is open circuit, ordered new thermostat kit tod and that should cure it. 😀

Thanks Jim,

THE NTC is rarely open circuit but it will give that impression with a simple continuity test, you need to use a resistance test on the NTC. 😉

Resistance should be around 500kΩ at room temperature.

There are not two TOC’s, one is a cycling thermostat and the other is a one shot TOC. Some models only have a single TOC and NTC, the cycling stat has been taken off then put back in at least once.
