Firstly we need to make sure that HOTTAP is actually not lighting. Look through the front slit holes on the unit and see if you can notice a blue flame appearing across the burners. If you can, refer to this article.
If the unit is definitely not lighting, try the below:
No clicking and LED screen doesn't power on:
The HOTTAP needs adequate water pressure to operate correctly, so if nothing is happening, check the following:
- Make sure the water hoses are on correctly (cold water in on right hand side, hot water out from the middle). If the hoses are back to front the Hottap won't turn on.
- Make sure the batteries are making contact with the springs and metal tab inside the battery box. Try pushing the battery box further into the unit and see if that helps.
- Check for sufficient water flow and pressure.
- Try the Hottap on mains water. If it works fine you can work backwards to figure out what is restricting the flow to the Hottap.
- If you are using a 12V pump, ensure the pump battery is fully charged. If the battery is only 50% (for example) the 12V pump will put out a lower flow and pressure than it should.
- If you're running on tank water or a gravity fed system you may not have enough pressure to turn the Hottap on, try the next step below.
- Adjust the ‘water flow’ setting on the HOTTAP to ‘LO’. This will make it easier to ignite (in case it is a water flow issue). If you find that the HOTTAP ignites when set to ‘LO’ water flow but turns off when the ‘Water Flow’ is adjusted higher, see this article.
- Check for blockages in your water lines that could restrict water flow. Unscrew your blue quick connect adaptor on the water inlet, and look inside the brass inlet fitting to make sure the mesh is clear. Make sure to clean the inline filter on your pump also if you have it.
- To flush the system, connect the input water source to the ‘Water Outlet’ and turn on. Once complete, reconnect the appliance as per instructions.
I can hear clicking and my LED Screen Lights up, but there is no ignition:
- There might be a slight air-lock in the gas lines. You can try to clear it by purging the gas:
- To do this for HOTTAP V2, have your gas bottle 'Open' and simply disconnect the gas hose from the gas inlet. A little bit of gas will leak out as you disconnect but then it will stop flowing because the gas connection has a stop-valve fitted. Wait a few seconds and connect it again.
- To do this for HOTTAP V1, have your gas bottle 'Open' and slowly unscrew the inlet gas connection on your Hottap until you hear gas seeping out. Let it purge for a few seconds and re-tighten. Wait 30 seconds for the gas smell to disappear and try to ignite the Hottap.
- Try to use a new set of brand new batteries. If batteries run low, they will have enough power for the ignition (the tick tick tick you hear), but not enough power to open the gas solenoid (this is the part that lets gas flow into the Hottap).
- Ensure that you're using either a 4.5kg or 9kg LPG bottle. Also, make sure that you open the valve on the gas bottle fully. Needless to say, make sure the bottle is not empty.
