Hello,
I have a 2yr old Lenox furnace, it wont ignite. I have two indicator lights that give me a code as to what might be the problem.

It activates the ignitors and they get hot, but never ignite the chambers. It kicks off the ignitors and then tries again. After a few tries, it give me this flashing light and the chart says it could be one of the following things:

- Pressure switch is open or has opened 5 times in a single call

- Blocked inlet/exhaust

- Pressure switch closed prior to activation of combustion of air blower

Please help me out guys, its a brand new unit.

Thanks Brian

Sorry, posted in wrong place......

About your dishwasher, I have heard that it can be your water. Water with alot of setiment and minerals can leave a film.

I would bet yur town gets its supply from wells.

I hear water softeners are the fix.
I have the same problem but just havent got the cash for the softener right now

Good luck, let me know

White film. Possible calcium. If it washes off by hand you have a drain problem. Not all the water leaving the D/W.If it doesnt come off by hand try cleaning with vineagar. If it is removed then it is most likely calcium from the water.
