HydroPower
Cause
Insufficient water supply pressure.
Dirty taps or mixers.
Water valve blocked (filter).
Heat exchanger blocked (limescale).
Explosive ignition is not normal
behaviour.
This is not normal behaviour.
This is normally caused by blockages in
the burner causing poor combustion.
One of the causes of blockages is insects
blocking burner orifices, this cannot be
avoided as adequate air flow is required
for complete combustion.
Old appliances
Old appliances contain valuable materials that should be
recycled.

Solution
Requires a service technician to inspect
and test water supply pressures, and
water components of the hot water unit.
Call a qualified technician.
All gas appliances require adequate air
flow for proper combustion. The ingress
of insects or dirt into the unit are not
covered by warranty as a manufacturing
fault is not present. The unit will need
cleaning and servicing at the owners' cost.
To minimise the chance of the issue
recurring, a surface type insecticide can
be used with care, consultation with a
licensed pest controller is recommended.
Isolate the valves to the unit and spray
surrounds with a surface spray.
Leave for 15 minutes before turning hot
water on.
If the unit is located a long way from the
outlet there will be an amount of cold
water that has to leave the pipe before the
hot water is available. As the hot water
unit does not operate at a large flow rate
this may appear to take a long time,
particularly if it has replaced a mains
pressure storage heater.
Open hot tap to full to increase flow rate
and reduce time.
