Isolate appliance and carry out:

B:Insulation check. Rectify any fault including replacing fuses as necessary.

A. EARTH CONTINUITY CHECK - Appliance must be electrically disconnected - meter set on W (Ohms) x 1 scale and adjust zero if necessary.

a)Test leads from any appliance earth point to earth pin on plug. Resistance should be less than 0.1 ý (Ohm), check all earth wires for continuity and all contacts are clean and tight.

B. INSULATION CHECK - Appliance electrically disconnected, all switches ON.

a)meter set on W(Ohms) x 1 scale.

Test leads from L to N in appliance terminal block. If meter reads «0» then there is a short circuit.

b)meter set on W (Ohm) x 100 scale.

Repeat test with leads from L to E. If meter reads less than × (infinity) there is a fault.

NOTE - Should it be found that the fuse has failed but no fault is indicated - a detailed continuity check (i.e. by disconnecting and checking each component) is required to trace the faulty component. It is possible that a fault could occur as a result of local burning/arcing but no fault could be found under test. However a detailed visual inspection should reveal evidence of burning around the fault.
