My Portable Water Heater Won't Light: No Clicks

My Portable Water Heater Won’t Ignite: NO CLICKS!

If your portable tankless water heater is having trouble igniting, there are a few things to take into consideration while trying to figure out the reason behind it.


  • What is your water source?
    • You must have at least 25 psi (pounds per square inch) to activate and keep the water heater running.
    • If you’re using a pump, there will be fluctuations in the pressure depending on the type of pump you’re using.
    • If you’re using city water with adequate water pressure, then you may need to think of doing a water pressure adjustment or it could be something else. *See Water Pressure Adjustment article.
  • Are you hearing clicking sounds when it tries to light?
    • Yes?
      • Check to be sure the flame sensor is hooked up and for sure connected.
      • Disconnect your incoming water line. There is a screen immediately inside of the incoming water pipe that may have clogged over time and is reducing the water flow and water pressure. (Clean that out if needed)
      • Make sure your gas is on and open.
    • No?
      • You may not have enough water pressure to activate the water heater.
      • Pull the little metal lever on the micro switch to see if you hear clicking (NOTE: Water heater must be in the upright position for this step).

      • If the microswitch doesn’t make the clicking sound when checked manually, it is most likely your ignition pack.

Please be sure you are checking to the following:

  • Fresh batteries (Inserted correctly?)
  • Full propane tank and it's open/on
  • The switch on the bottom is in the “ON” position
  • The battery for your pump (if you’re using a pump) is still good 

Remember: The CE-L5 is equipped with a safety tilt switch that will shut the water heater off if it’s tilted too much to the left, right, front or back. This water heater must be in the upright position for the microswitch and water heater to activate.

Please keep in mind that the CE-L5 is NOT to be permanently mounted or left unattended as it is not recommended and can be considered a hazard. Not for indoor usage or to be vented. Also, these units are not to be plumbed in to the side or any other part of the house or location and is meant to serve for recreational use only. Using in the manners stated will void your warranty.***

How old is the water heater?

Last thing to consider is the age of the water heater. When was the last time the water heater was flushed and descaled? Over time, sediment can build up inside the pipes of the exchanger and restrict water flow, causing the water heater to overheat and shut off.
