Service Analyser Codes
Code Problem - Action / Remedy
LP, LP3 Problem: Low refrigerant level in the pool heat pump or the low-
pressure safety control is defective.
Atmospheric conditions as well as the pool water temperature
should not be below the minimum operating temperatures, as stated
below, in order to obtain efficiency and avoid codes from appearing
on the electronic control temperature display. These codes are not
generally a problem with the pool heat pump at these conditions and
are not covered under warranty.
If temperatures are below the minimum temperatures the pool heat
pump should not be operated and must be switched off.
Action / Remedy:
- If the LP or LP3 code is shown permanently, press SET or ON/OFF
- Ensure the evaporator is clean. If not, switch the unit OFF from
- Ensure installation instructions have been followed. Improper
HP, HP3 Problem: Low water circulation in the unit or the high-pressure
control is defective. If the HP code is triggered and displayed 3
times; this will cause the pool heat pump to shut down automatically.
The HP3 code will then appear permanently (except for reversible
(XLR) electronic control with diagnostics).
Note: The pool pump will stop functioning only if the internal time
delay of the pool heat pump is being used.
IMPORTANT: When the code HP3 is permanently displayed, before
performing the steps below, please press the SET button for the
Multi Function electronic control and ON/OFF for the electronic
control with diagnostics and the reversible (XLR) electronic control
with diagnostics.

depending of the model you have, before getting to the next step;
the circuit breaker (fuse) and use a garden hose to lightly clean
the evaporator. Allow it to dry before re-starting the pool heat
pump to avoid premature ice build up on the evaporator.
installation, e.g. no air circulation, could lead to the pool heat
pump continually going into LP or LP3 mode and the installation
will need to be corrected by the owner. This situation is not
covered by the warranty.
