There seems to be a problem with the electric pump
If you are having problems with the electric pump, use this guide to find the source of the problem:
first check the obvious: is the electricity supply switched on?
has the circuit breaker tripped or a fuse blown?
look for an obvious cause, e.g. water or beer has dripped onto electrical equipment
if possible, remedy the cause, then re-set the breaker or replace the fuse
if the breaker trips or the fuse blows again, call an electrician - do not touch the equipment.
