Solutions
D.
Safety Valve Fused
(melted or
has an opening)
Replace safety valve with a genuine Hawkins safety valve (see
Parts, Do-It-Yourself Repairs
and Service
,
pages 84–89).
1.
Excessive heat
from heat source
a. Do not use cooker on an industrial burner/stove – use only on a domestic burner/stove.
b. Use a burner to suit the size of the cooker – gas flames should not lick the sides of the
cooker and the hot plate of an electric stove should be of a diameter not more than that of
the base of the pressure cooker.
c. When cooking in the 1.5 Litre, 2 Litre and 3 Litre cookers (except 3 Litre Wide), the 4 Litre
Contura and the 4 Litre Contura Black, use the small burner or do not exceed the medium heat
setting of a large burner.
2.
Cooker boiled
dry
a. Always ensure there is enough water/cooking liquid for the entire cooking time
(see
Cooking Tips
,
page 20,
Water
).
b. Reduce heat to medium or lower as soon as pressure cooker reaches FOP (see
Trial Run
,
page
16, point
5. How to Recognise Full Operating Pressure
(FOP)
and point
6. Maintaining
Pressure on Reduced Heat
).
c. Time accurately and remove cooker from heat when the pressure cooking time is
completed (see
Cooking Tips
,
page 21,
Timing
).
3.
Vent tube/
vent weight
blocked
a. Always check that the vent tube is clear by looking through it before closing cooker
(see
Trial Run
,
page 15, point
2. Placing Cooker on Stove
).
b. Clean vent tube and vent weight after cooking.
c. Do not fill cooker more than the stated capacity (see
Getting to Know Your Hawkins
,
page 9,
Food Preparation
and
Maximum Cooking Capacities/Volumes for Different
Sizes of Hawkins
,
page 41). Avoid sprouting to prevent clogging the vent tube (see
point
