We have a Raypak 406A, about 6 years old. Had intermittent problems last year with it not firing up or not bringing the water up to the desired temperature.
Problems started again. After igniting once and not bringing the temperature up to desired level, it just stopped igniting. Error code reads PRS. We made sure the filter was clean and replaced the pressure valve. Didn't work.
We replaced the gas valve. Didn't work.
We replaced the pilot mechanism. You can hear the ignitor "ticking" but the pilot won't light. It did light manually and ran for a while, but did not bring the temperature up to desired level.
Next step? Circuit Board?
Also, could the transformer be bad and not putting out enough voltage? Does that happen?
