Hi,

I've had the Rocket Classic for two years now. After being on for some time the green light is still ON, but the pressure drops to 0. I guess the heater turns off for some reason. I suspected it was the preasurestat, so I replaced it with a new MATER, but the problem persists.  Any ideas on what could be causing the problem?

Thanks,
R.

It may be thinking the reservoir is empty.
Do you use reverse osmosis or distilled water?  If so, add a cup of tapwater to the reservoir.
It might just be air in the reciever under the reservoir, lift and lower the reservoir twice. make sure it seats all the way down...
Though on the newer Rockets, the green light would blink if it thought the reservoir were empty.
It is also possible that the powerboard is failing in some way.

I do not use distilled water, and yes on my model the light would blink if the reservoar was empty.

The powerboard seems plausible, since flipping the power switch OFF, and than back ON, causes it to start heating again. Would I be able to get a replacement powerboard, and replace it my self? Or am I better of taking it to service?

Thanks.

You could replace it yourself, it's a matter of pulling off and pushing on about 10 push-type connections from the old to the new.  A replacement board wouldn't be cheap, I'd make sure to exhaust all other possibilities, first.

Is your Pstat a Mater (Circular) or a Sirai (Big Box)?
Is your powerboard controlled by the Pstat? 2 wires from P-Stat both run to the powerboard...
Or is your element controlled through the P-stat? One wire from the P-stat goes to the element (Or through the safety to the element) the other goes to the power board (Or through the safety to the powerboard)

If you're comfortable running the machine with the right-side wall off.  Use it normally until this problem occurs...  Once you have the problem, see if you have voltage at various locations to determine the cause.
Smack the p-stat to see if that starts it working.  Smack the powerboard to see if that starts it working.
