The new IDF125 Indesit dishwasher has changed design, the look of the dishwasher hasn’t changed too much but internally  there is a big difference. The wash pump motor is made by Askoll, this isn’t a motor as we know it.  The impellor on this thing vibrates and aggitates back & forward. I have replaced two of these pumps already due the impellor  falling off the motor shaft. The Indesit IDf125 has a 31.8 ohm heater is seated on the end wash motor housing, both these and the other components situated in the base of the dishwasher are accessed via a plastic panel in the bottom of the dishwasher.
