Unit ignites but then goes on/off with pressure error.
Pressure is good
RP2100 model 277 approx 10years old. Has had 2 new temperture control panels ,2 x new pilot assemblies , new headers , burner box insulation and quite a lot of the sheetmetal has been replaced. Up untill lastseason was working well. All functions appeared to be normal.
However , currently the unit will not stay alight. once it lights it runs for 5 secs , stops nd goes through the re light process. This continues untill i turn it off . Any suggestions ???

If you received the PRS error, then it is the water pressure switch. The water pressure switch, or heater actuator, ensures
that the heater operates only when the filter pump is in
operation. It is located on the inlet/outlet header. It is
factory set at 1.75 PSI for deck-level installations.
When the heater is located below the level of the spa
or pool, it may be necessary to adjust the pressure
switch to compensate for the no-flow static head. If it
is necessary to adjust the water pressure switch, Follow the directions in your manual.If your is the low Nox model, then you have a combustion fan. This has a fan air pressure switch but the error code for it is FAN I believe. If you don't have a manual you can get one at www.raypak.com
