Reasons
1. From your statement, it seems the machine always fails between temperature 90C to 110C. This is very popular problem for Pelton & Crane Validator or Delta (New generation after Validator.)

Because durinmg 90C to 110C, in order to let the air out of the chamber, the vent solenoid is in the ON/OFF/ON/OFF mode. After 110C, the valve will close completely. Your machine faied, because its Pressure and Temperature sensors is out of calibration (Most case is the temperature sensor out of calibration, even the real temperature is higher than 110C, but its reading still in 107C)

Unfortunately Pelton & Crane, does not allow customer to do the calibration work on site. This is one reason we would suggest our customer to buy Tuttnauer E machine, which has same functions, but provide customers more trouble-shooting and tech support.

you submitted the question in our Delta category, but mentioned your machine name Validator. We need you to confirm which model you have. Their parts (Validator and Delta) are NOT exchanble.
2. Sometimes, if the main PCB board fails, it will cause this problem too. That is why Pelton & Crane always suggest their customers to change the main board completely. It will solve the problem.
