Fault Finding Tests 6A – 8
Test 6A (3 – 15L models)
Disconnect the two wires from the boiling
water element and using a multimeter on the
ohms scale, measure between the two
element terminals. The following result should
be obtained:
3L models (1.8kW element):30 – 34 Ω.
5L–15L models (2.4kW element):22 – 26 Ω
Disconnect wiring at inlet solenoid valve and
using a multimeter on the ohms scale,
measure between the two terminals of the
solenoid. The following result should be
obtained:
