Possible cause 3:
NOTE: In some cases, the thermal safety cut-out tripping and a low flow rate can be linked
i.e.: when a filter becomes choked air can be drawn into the filtration system and
become trapped inside the heater so causing the cut-out to trip.
If using a sand filter: Check the pressure indicator on your sand filter and back wash if necessary.
NOTE:
➢ No light appears on the heater when it is switched 'on':
Possible cause:
Remedy:
➢ Heater is tripping circuit breaker (MCB) after few minutes/ hours of operation:
If the heater is faulty it will instantly trip the circuit breaker (MCB). The most likely causes of tripping
the breaker after a period of time are:
Possible Cause 1:
Possible Cause 2:
Possible Cause 3:
Possible Cause 4:
Remedy:
➢ Heater is tripping circuit breaker (MCB) or RCD instantly:

Insufficient flow. - if this is the cause the display will show 'No Flow'.
If using a cartridge filter: Confirm this by running the system with the cartridge
removed from your pump & filter unit, this will supply the heater with the maximum
flow rate that your unit is capable of. If the heater then switches 'On' a blocked
cartridge can be confirmed to be the cause. The cartridge should be cleaned or
replaced.
If using a sand filter: Check the pressure indicator on your sand filter and back
wash if necessary.
In some cases, the thermal safety cut-out tripping and a low flow rate can be
linked i.e.: when a filter becomes choked air can be drawn into the filtration
system and become trapped inside the heater so causing the cut-out to trip.
Power failure external to the heater
Check any fuses, RCD or other switch components installed in the supply cable.
Note: The heater is fitted with a 3 Amp glass fuse located on the top control panel
assembly (see Fig 1).
Faulty circuit breaker.
Incorrect size of the circuit breaker.
Cross section of the cable is not sufficient.
Loose connection(s) of the power supply cable. Check both ends of
the power supply cable (at the distribution box and at the heater
terminal block).
Contact an Electrician to check installation and protection.
Short circuit caused by the wiring or faulty components.
Heating element is going to ground or is damaged.
Moisture inside the heater.
Contact an Electrician to check installation and protection. Send
heater back to the manufacturer. Use return form on page 25 or
download it from the Elecro website.
