If limescale is produced inside a warewasher it will cause a
number of maintenance problems, for example:
Coating of heating elements leading to slow heating and

eventually, element failure.
 Blockage of rinse jets, showing as poor results.
Wear of bushes in the centre boss, showing as poor results

and possibly wash water passing backwards into the rinse
system.
Blockage of the rinse aid injection point in the boiler.

White marks appearing on glasses, dishes and cutlery.

 Dishes or cups may appear dirty even after a wash.
Especially coffee or tea cups.
Discolouration of the inside of the warewasher, making

cleaning difficult.
Blockage of hoses due to limescale deposits "furring up" the

inside of the hoses.
When limescale is found, it must be removed with commercial
de-scaling chemicals, used with care in accordance with the
instructions on the product.
The descaling instructions in this manual should always be
followed.
The Rinse Tank is difficult to de-scale and a service engineer may
be required to carry this out.
Your local water board / water supply company should be able to
tell you if the water in your area is hard or soft.
Alternatively you can establish the hardness of your water supply
yourself using a simple water hardness testing kit.
Water Softener settings:
Your Water Softener needs to be set up to soften the water
supply depending on the water hardness, according to the
following table:

4.7.3 Water supply hose connection
Classeq recommend installing a shut off valve in the mains water
supply line near the warewasher such that it is easily accessible.
The warewasher is supplied with a new UK Water Regulations
Advisory Scheme (WRAS) approved water inlet hose, requiring a
G¾" (¾" BSP) male threaded connection at the mains water
outlet.
Connect the 90 degree bend connector of the water supply hose
to the inlet on the back of the warewasher and the straight
connector to the mains water supply.
