Lay-Z-Spa pumps have to be plugged directly into a grounded mains supply. Please see the checklist below for further information:

Where is the item plugged into?

•            Is the pump plugged into a single of double socket?

•            Is the pump being used with an extension lead?

•            Are there any other items plugged into the same socket?

•            Is the plug socket outside? If so, is the socket waterproof?

•            How old is the plug socket?

•            Is the plug socket connected directly into the mains or is it a spur?

•            Are there any other household items tripping?

•            When was the last time the socket was tested by an electrician?
