SERVICELINE TIPS & HINTS

WAREWASHING

1. Regular cleaning will improve the life of pumps and help provide the best quality wash by keeping the machine clear of waste products. Clean out the strainers regularly, and at least twice a day. Check the strainers are not damaged and that they are fitted correctly so as to not allow waste residue/utensils to pass through which will damage pumps and possibly cause blockages especially in energy recovery devices. Replace immediately if damage is evident. Cutlery in wash pumps is one of the major causes of failure.

2. The larger the dishwasher, the greater the need for good staff management and training. Check that doors are put back in position correctly before making a breakdown call. One call recently on a big flight machine was caused by a door safety switch which was telling the control system the door was not closed properly. It had been knocked out of line through being accidentally hit as a strainer basket was removed. In this case, it needed a repair, but these switches can cause unnecessary expense when damaged. Always ensure curtains are fitted and in the correct place, this will reduce the heat loss and help to maintain the correct temperature in each section.

3. Operating temperatures – if the machine is displaying temperatures which are different from the manufacturer’s recommendation, have the machine checked urgently to avoid hygiene risks. It is vital that the final rinse temperature maintains 82 degrees C for proper machine performance. The temperature of the wash water is also important, to low a temperature will cause excessive detergent foaming, generally the water needs to be between 55 & 65 degC. Always keep hoods and doors closed when machines are not in use.

4. If the machine cycle is longer than usual don’t assume there is a problem with the machine, outside influences can affect machine performance e.g. low temperature of incoming water in winter-time, room temperature and the use of machine outside its operating parameters.

5. When the engineer calls for a breakdown or routine maintenance visit, do you really want to pay them for clearing access to the machine or cleaning gunk and dirt away to get inside? It is simply ridiculous to have an engineer move a massive pile of dirty plates before he can take a look inside the machine or clear debris from filters or wash arms, which should be done in routine cleaning.

6. If after all that cleaning, the dishwasher still has a cloudy off-white coating inside, that is limescale building up which will constrict pipework, make the pumps work harder and damage heating elements. Check your water softener is working properly. It should be easily accessible to allow regular top-ups with salt, which staff can forget to do. If it seems to be working OK, it may need adjusting to regenerate more often.
