kenxq5471 Posted April 20, 2009 Report Share Posted April 20, 2009 When I first tried to light my Laars propane water heater I get a warning indication of "low pressure", yet the pump is running with good pressure. Any ideas? It just won't ignite. Quote Link to comment Share on other sites More sharing options...
lehighcustompools Posted April 21, 2009 Report Share Posted April 21, 2009 When you say good pressure, do you mean as measured on your filter? If so, is your displayed pressure high or low? High pressure on the filter means dirty medium and low pressure at the heater. Otherwise...bad sensor? Blocked return? Try putting the system in filter bypass and see if it works.

Pool Clown Posted April 21, 2009 Report Share Posted April 21, 2009 the pump is running with good pressure. Any ideas? It just won't ignite. How much is good pressure? Is this the pressure it normally has? "Good pressure" or high pressure at the filter gauge means lower pressure to the heater. Make sure the filter is clean, also the pump basket and skimmer basket(s). Quote Link to comment Share on other sites More sharing options...
Laars Pool Heater Posted September 14, 2009 Report Share Posted September 14, 2009 When I first tried to light my Laars propane water heater I get a warning indication of "low pressure", yet the pump is running with good pressure. Any ideas? It just won't ignite. Could be a few things - have you checked the pressure switch? Quote Link to comment Share on other sites More sharing options...
