Re: indesit wd125 error code?? three flashes
As Dave says its almost certainly a OC thermistor / wiring fault.
Easist way to check is to slip the plug of the thermistor and measure (using a multimeter) the resistance across the plug terminals. If there is no open circuit (broken connection) you should get a reading of about 13k ohms through the module.
The thermistor itself should measure about 24K ohm at room temp.
