Carry out the performance checks, and if your machine cuts out unplug and leave for at least 2 hours to cool down.

If the customer prefers to check the machine when the power has returned, wait for a minimum of 2 hours and ask them to call back.

The filter should be washed every three to six months. The post-motor filter located under the clear bin should last the lifetime of the machine and does not need to be washed. Please do not remove this filter.
