Possible cause
Short circuit in the flow,
return or boiler temperature
sensor.

General

The Remeha Avanta has an advanced control unit. The heart
of this control unit is a microprocessor, the abc
both controls and protects the boiler. If an error is detected
anywhere in the boiler, it will lock out and an
error code will appear in the display.

Error codes

The Remeha Avanta displays the error codes as follows:
é 2 (the display alternately shows an é and a number e.g.
2)
The meaning of the various error codes can be found in the
error table, see table 11.
How to deal with errors:
• Make a note of the displayed error code.

The error code is important for the correct and swift detection
of the nature of the error and for possible support from our
technical help line 0118 978 3434.
• Press the 'reset' key for 3 seconds. If the error code con-
tinues to appear, look for the cause in the error table below
and resolve it.
Check / solution
Check the wiring and the connections of the sensors visually: are the
plugs all correctly in position? With a multimeter: measure the resist-
ance in the wiring and connection.
Check that the sensors are working; take the sensors out* and
measure the resistance with a multimeter at room temperature
(20 - 25°C); the sensor is working properly if the resistance is
between 12 and 15 kΩ
Check the water level and check for leaks.
Check that the pump is working; turn the spindle with a screwdriver,
if that works but the pump still does not respond, check the wiring; if
that is in order the pump is faulty.
Check that the sensors are working; take the sensors out* and
measure the resistance with a multimeter at room temperature
(20 - 25°C); the sensor is working properly if the resistance is
between 12 and 15 kΩ
