TS: L5 will not start and no sound of clicks

Portable tankless water heater will not start – there are no audible clicks at startup:

  1. The first thing to check is to ensure that the incoming water on the “right” side of the portable tankless water heater. If the incoming and outgoing are reversed, the portable tankless water heater will not work. The incoming is on the far right and the outgoing is in the middle.
  2. The “On/Off” switch should be with the”-” sign pushed down.
  3. Check to make sure you have fresh batteries and they are installed in the correct position.
  4. Number one reason that the portable tankless water heater does not ignite is that there is not enough water pressure. You need to make sure that you have a minimum of 20 PSI of sustained water pressure.

ADJUSTMENT: Looking up at the bottom of the portable tankless water heater, you will see 2 oval holes in the case. The hole that is furthest on the right looks up at the water regulator where you will see two Phillips head screws. Take the screw that is furthest on the right in about a 1/4 or 1/2 turn. This will enable the portable tankless water heater to operate on a lower water pressure by restricting flow.

There is a simple test that we can help you perform if you are unaware if you have enough water pressure. Please visit the Eccotemp helpdesk at www.eccotemp.com/helpdesk or contact us via email at support@eccotemp.com for additional troubleshooting steps.

  1. A wire has become disconnected inside the portable tankless water heater during shipping. Make sure the gas is OFF and the switch is in the OFF position. The front cover is held by four screws, two on top, two on bottom. The knobs pull off. All the wiring is done with push together plastic connectors. They are all visible without further dismantling of the portable tankless water heater. It should be obvious when a wire has become disconnected.

NOTE: Before attempting to remove the cover, call technical support at 866.356.1992

  1. It is possible that some debris or epoxy might have entered the water regulator. Check to see if the filter screen on the water inlet is clear of debris. You can also reverse the hookup by taking your water source and hooking it up to the water outlet side and back flushing the system.

Propane gas cylinders sometimes are contaminated with air, especially new tanks upon their first filling. Cycle the portable tankless water heater on and off by using the shower head switch several times (5) to purge the air from the gas.
