water heater ignition

I have a suburban sw6de water heater. When i try to start it using propane i hear the clicking sound and then it locks out, after about two times then i get an explosion of built up gas. Sometimes it takes 15 to 20 attempts before it starts heating.

Mine does the same thing....except it just clicks and no gas. Sounds like the valve is the culprit. Does it work on the Electric Element?

Try purging the air out of the gas line by turning on one of the stove burners for a minute or so. Once you get a good flame going turn the stove off and attempt the WH again.

did that. twice. furnace, stove, fridge all work immediately upon trying. loosened inlet to valve - did bubble test - getting flow to valve. checked fuses - all good. checked connection - power at 110 at each connection (of the four) - resistance across 3&4 switch connections, but nothing across 1&2.

Sounds to me that you need to check for little critters (spiders, wasps, etc) that have taken up residence in the venturi,manifold system. Compressed air and/or a small round fairly stiff brush should take care of the problem.

Sorry....left out that step. That was the first thing I did - check and run a bottle brush through the tube to make sure no critters had taken up residence.

If you are getting a small explosion then you are getting gas into the heater no problem. The problem is you are not getting ignition. I had a problem like that. The spark 'thing-a-ma-jig' had to be adjusted closer to the fuel outlet. It took a dealer 2 minutes to adjust it (not even the trailer dealer) and no charge.

I'm getting the spark - just not getting any gas. Even holding a lighter up at the opening of the gas tube - nothing. My problem IMO is the valve, not anything electric. The ignitor (the spark thing-a-ma-jig) sounds like it is the problem for Homer.

The electric side works, but not quite as hot as gas heating. Thanks for all the input, i will try to blow out the wh with compressed air. I think it's the electrode or valve, not very familiar with this stuff.
