Water Heater
4.11 iVan Communication PCB AK1226
The iVan Control Panel uses a wireless communication protocol to transfer user settings to the
Water Heater and to receive operational data from the Water Heater. Issues in relation to the
wireless communication can occur in two areas (see Figure 19):
-pairing of iVan Control Panel to Water Heater
-Water Heater communications PCB hardware issues
The iVan communications PCB fitted to the WI Water Heater does also control the Pump in the
vehicle. Checking the Pump functionality therefore gives a good first indication of the status before
any of the appliances need to be opened.

Ensure 12 V DC
power supply is
switched on
✓
Unplug 230V
mains JST plug
from supply
Insert multimeter to
check resistance
measurement across
live and neutral as
shown
Should the above not resolve the issue:
1
st
check resistance of electric element
2
nd
replace electric element
- compare measured value with relevant
reference value in table above
- should the measured value be considerably
higher than the reference value the element is
faulty and requires replacement
Drain down Water Heater.
Note positions of wires
