9.  Troubleshooting 

9.1 General

Your  product should give trouble free operation. 

However if  a problem occurs the table below should 

allow most faults to be identified. Fault finding should 

only be carried out by a competent person.

For  any  faults  that  cannot  be  identified  using  the 

fault finding chart please contact the Heatrae Sadia 

Service Department.

Symptom

Possible cause

Remedy

1. Water too hot

A. Water flow too low

Increase the flow by turning the stop valve

2. Water too cold

A. Electrical power to the 

Multipoint heater is off

Ensure that the electrical supply to the Multipoint

B. Water flow too high

Reduce the flow by adjusting the water control 

isolating valve

C. Element fault

Check for open circuit

3. Temperature 

varies while 

showering, cycling 

hot/cold

A. Pressure switch is operating, 

normally making a "click" as it 

does so

Check water pressure/flow

B. Input pressure is below 1.0 bar 

(14.5psi); flow is not stable

Ensure that your stop cock and servicing valve 

are opened fully

4. "Power on" 

indicator not lit. 

Isolating switch "ON" 

but its neon not lit

A. Cartridge fuse or miniture 

circuit breaker (mcb) has 

operated in your fusebox (or 

consumer unit) or switch fuse

Switch off Multipoint Instantaneous and isolating 

switch. Renew fuse, reset the mcb. If they 

operate a second time, contact a qualified 

electrician

B. Residual current device (rcd) 

or (earth leakage circuit breaker)    

has operated

Follow the same procedure as above. If this has 

happened with a "split load" consumer unit on 

initial installation, check that the neutral core 

of the Multipoint Instantaneous feed cable is 

connected to the "protected" neutral bar of the 

unit

5. Water emerges 

from expansion 

relief valve

A. Expansion relief valve has 

operated

1. Switch off immediately at isolating switch  

2. Turn water off at the servicing valve (if fitted)    

or stop valve  

3. Contact Heatrae Sadia Service Department

6. No water flows 

with valve open

A. Water supply turned off

Turn on water supply

B. Unit frozen

Turn OFF ELECTRICITY at isolating switch 

and contact installer DO NOT USE THE 

MULTIPOINT INSTANTANEOUS
