Does anyone know if this is their correct state ? Thanx for any help, Albert October 4, 2004 at 4:03 pm #117481 Dave_ConwayParticipant Re: Ariston AF300 d/w not heating The screw in one near the heater is described as thermostat safety 78 NC The other “two” are actually one part and is described as thermostat 50/62 NO So it would appear that they read OK. Timers are a common failure on these, pull all the plugs off and check for burnt terminals 😉 Dave.
