Important: Disconnect mains electricity supply before handling or attempting maintenance. Always fully read and check the troubleshooting section within your product instruction manual. 

In order to investigate why your wavemaker is not working you must first open up the unit and take a look at the impeller and shaft. Inspect these parts for damages or blockages and clogging. You will need to remove the motor head and check that the impeller and the shaft are intact, unblocked and in place. Ensure that the plastic propeller part of the impeller is attached to the magnetic part and that they have not come apart or split. If these parts looks fine and there are two rubber grommets fitted on each end of the shaft, or already inside the fittings, then please re-assemble the unit.

It is a good idea to check the fuse and try plugging it into a different plug socket - this can sometimes be the cause for this type of problem. 

If your unit is still not working please contact us our customer services team who will be happy to advise further.
