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:
I can’t hear the ignitor clicking at all
- Ensure new batteries are installed in the correct polarity (+/-). Check the cap of the battery case for instructions on how they should be installed.
- Check that the batteries are not expired (sometimes stores will have batteries sitting on the shelf for a very long time, causing them to expire before purchase).
- Make sure that your hoses are the right way around. The water outlet (red hose) should be connected to the middle fitting, and the water inlet should be on the right hand side.
- Check for sufficient water flow and pressure. The unit must have a minimum of 45kPa of sustained water pressure and at least 4LPM to activate the burners. If you are using a 12V pump, ensure the 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.
- Adjusting the ‘water flow’ setting on the HOTTAP to ‘Low’ will make it easiest to ignite (in case it is a water flow issue). If you find that the HOTTAP ignites when set to ‘Low’ water flow but turns off when the ‘Water Flow’ is adjusted higher, see this article.
- There is the possibility of finding some kind of epoxy or debris within the water regulator. Check that the water inlet filter screen is clean. 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
- If you can hear ‘sparking’, but no ignition, air may have contaminated the gas inlet. Unscrew the inlet gas connection a few turns until you can hear gas seeping from between the thread. Let it purge for a few seconds and re-tighten. NOTE: Gas hose must be attached to the inlet thread while purging. NOTE: Gas cylinder must be on, ‘Open’.
- 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.
- Check your batteries. If you hear a spark but no ignition, your batteries may be drained to the point where they have enough juice to supply power for the sparker, but not enough to open up the electronically controlled solenoid valve (this is the part that allows gas through). Even if your batteries are brand new, check the expiry date as sometimes batteries sit on store shelves for quite a while before being sold.
