5. Failure of Hot Water Supply on Shore power. In the event of a failure of
electrically-heated hot water (not engine-heated), check the following:
a. Check that the hot water is switched on at the rotary switch on the outboard
wall in the starboard cockpit locker. If ON, the first course of action should be to cycle
the switch and wait 20 minutes for a reaction.
b. After cycling the switch and still no warm/hot water, although there is good flow
from the hot water taps, it is possible that the thermostat has failed to control the
temperature, followed by operation of the thermal cut-out protection switch. Proceed
as follows:
•
•
•
•
Remove all contents of the starboard cockpit locker, leaving the
floorboards fully exposed (1 above).
Remove the forward inner floorboard to expose the top of the hot water
tank, (2 above). Check the tank is cold to the touch.
Press to reset the thermal cut-out on the top of the tank as shown in
Photo C.
In all cases, please
