FAULT FINDING & SERVICING

IMPORTANT

• After servicing, complete the relevant Service Interval Record for the installation.

• Servicing should only be carried out by competent persons in the installation and maintenance of unvented water heating

systems.

• Any spare parts used MUST be authorised Mitsubishi Electric parts.

• Disconnect the electrical supply before removing any electrical equipment covers.

• NEVER bypass any thermal controls or operate system without the necessary safety valves.

• Water contained in the Air Source Heat Pump pre-plumbed cylinder may be very hot, especially following a thermal control

failure. Caution must be taken when drawing water from the unit.

SPARE PARTS

A full range of spare parts are available for the Mitsubishi Air Source Heat Pump pre-plumbed cylinder range (see Table 8,

page 37). Refer to the technical data label on the unit to identify the model installed and ensure the correct part is ordered.

You will need to quote the serial number which is printed on the data label.

FAULT FINDING

The fault finding chart (above) will enable operational faults to be identified and their possible causes rectified. Any work carried

out on this unvented water heater and its associated controls MUST be carried out by a competent installer for unvented

water heating systems. In case of doubt contact Service Support (see contact details on back page).

WARNING

DO NOT TAMPER WITH ANY OF THE SAFETY VALVES OR CONTROLS SUPPLIED WITH THE PRE-PLUMBED CYLINDER

AS THIS WILL INVALIDATE ANY GUARANTEE.

Table 7 - Fault Finding Table

FAULT

POSSIBLE CAUSE

REMEDY

No hot water flow

1. Mains supply off.

2. Check and open stock cock.

2. Strainer blocked.

2. Turn off water supply. Remove strainer and clean (see

maintanance section).

3. Cold water combination valve incorrectly fitted.

3. Check and refit as required.

Water from hot taps

is cold

1. BACK UP immersion heater not switched on.

1. Check and switch on.

2. BACK UP immersion heater thermal cut-out

has operated.

2. Check. Reset by pushing button.

3. Programmer set to Central Heating only.

3. Check. Set to Domestic Hot Water programme.

4. Air Source Heat Pump not working.

4. Check heat pump operation. If fault is suspected, consult

heat pump instructions.

5. Thermal cut-out has operated.

5. Check. Reset by pushing button on cut-out. Check

operation of DHW thermal sensor

6. DHW circulating pump not connected

correctly.

6. Check wiring and/or plumbing connections to DHW

circulating pump. Check isolating valves are open

Water discharges from

Expansion Valve

1. INTERMITTENTLY

Expansion vessel charge pressure has reduced

below 3.5bar.

1. See Maintance section for re-charging procedure.

2. CONTINUALLY

a. Cold water combination valve pressure

reducer not working correctly.

b. Expansion valve seat damaged.

2a. Check pressure from cold water combination valve. If

greater than 3.6 bar, replace pressure reducer cartridge.

2b. Remove expansion valve cartridge. Check condition of

seat. If necessary, fit new expansion valve cartridge.

Water discharges from

T&P Relief Valve

1. Thermal control failure. NOTE water will be

very hot.

1. Switch off power to immersion heater(s) and /or shut down

Heat Pump. DO NOT turn off water supply. When discharge

stops check all thermal controls, replace if faulty.

Milky water

1. Oxygenated water.

1. Water from a pressurised system releases oxygen

bubbles when flowing. The milkiness will disappear after

a short while.
