What to do if my Intellihot iQ1001 shows Ignition Failure?

If your Intellihot Water Heater experiences ignition failure, the water over-heat switch may have tripped, or there may be a faulty DSI, igniter wire, ignition connection, PCB, or a bad igniter. Also, low gas pressure could be the cause. You should check the pump and cross over solenoid, and inspect for electrical noise (DSI). Replace any faulty parts. Adjust gas pressure at the regulator, check/upsize the gas line, and check for gas line blockage.
