Check the voltage on the rating plate
conforms to the territory the appliance is
being used in.
Three flashing red lights
Three flashing red LEDs either indicates an overheating issue, an incorrect voltage supply issue or a non-recoverable
fault. The appliance will switch itself off. If the customer then disconnects the appliance before turning it on again the
appliance will most likely turn on for a very short period before switching itself off and exhibiting the three flashing red LEDs
again.
Overheat:
An overheat is mostly likely caused by a severely blocked filter (see p.20/21 for full cleaning details).
It is also worth checking that they are not using the product with the filter cage blocked (for example by their hand or
unremoved packaging).
Voltage supply:
The product is voltage specific albeit a fairly wide range (e.g. The UK product is rated from 220-240V so could also be used
in EU 230V and Hong Kong 220V). Using it outside that range will cause the product to not switch on (but should not cause
any permanent damage). Ask the customer if they have moved location/are on holiday etc.

Check the appliance has not overheated
due to extended continual use in a hot
environment. If the problem persists
arrange a repair/exchange depending
on local policy.
Carry out the ‘Three flashing white
lights’ checks on p.22. If the problem
persists continue with these checks.
