Problem 1- The Hotrun does not switch on when opening the tap
Causes- Usually attributed to water supply problems.
Ensure the pressure on the cold water supply is more than 100kPa,
while the Hotrun is in use.
-Too much back pressure in outlets or shower heads after the
Hotrun causing lack of pressure differential over the Hotrun
(backpressure through the cold)- Wrong flow restrictor installed.
-Maximum temperature cut out switches activated, due to air in
the Hotrun not released before switching on the electrical supply.
Problem 1 Remedies
-Correct the water pressure problems; remove any flow restrictors
in outlets.
-Disconnect the hot water flexi and run it into a bucket and see if
there is warm water coming through. If so the problems are being
caused by new tap ware or blockages in aerators or restrictors.-
-Seek electrical assistance to check power all the way to the
elements.
-If the cut-out has been triggered due to poor flushing of air from
system then RESET the cut-out by gently depressing button (ensure
electrical power is disconnected first).
