Steam Generator Manual
12. Maintenance
The single biggest problem with steam generation is the build up of scale resulting from dissolved
solids within the water. Scaling can cause the elements to fail, the water level sensors not to
function, premature failure of the O-rings resulting in leaks from around the elements. The extent
of the problem will vary according to the degree of hardness in the local water supply.
For all commercial operators we recommend the use of a water softener.
Expect 2500 hours element life, this can be serious depleted by poor maintenance.
All users commercial and domestic must ensure a regular maintenance routine to descale
the generator – the frequency of this will vary according to the degree of hardness in the
local water supply and the amount of time the generator is used for. Check the water for
hardness and arrange the descaling routine accordingly: -
High levels of hardness descale once every 50 to 100 hours of operation.
Medium levels of hardness descale once every 100 to 250 hours operation.
Low levels of hardness descale once every 250 to 1000 hours of operation.
To descale the generator use a solution of weak acid crystals (such as citric acid) mixed with water
Citric acid can be purchased from:

12.1. Descaling procedure
i. Firstly push the drain button to empty the tank, check the valve is draining. Once the machine
has finished draining isolate the mains power.
ii. Unscrew the top plate of the machine which says water level probe, disconnect the probes
wires with a flat screw driver and pull the probe out.
iii. Fill the machine using a funnel with 5-6 litres of pre mixed citric acid.
iv. Replace the probe and reconnect.
v. Heat the machine for 2 minutes.
vi. Leave the machine for 4 hours minimum
vii. Drain 2-3 times.
Follow the instruction supplied with the crystals and allow sufficient time for the solution to
dissolve the scale before flushing out the generator. For best results add to water, steam for two
minutes then leave overnight. Empty the next days and flush twice using drain cycle.
Faults arising from a result of a failure to descale the generator are not covered by warranty.
Because heating and cooling cause expansion and contraction it is important to inspect all the
water and steam inlets and outlets as well as their pipes and connectors on a regular basis to
ensure there are no leaks.
Clean the filter net in the magnetic valve according to the water quality in the location.
The condition of the wiring and electrical integrity of the generator should be checked regularly -
for commercial operators this should be at least once a year.
