    Can you run a dishwasher without hot water?

    Yes a dishwasher can be run without a hot water connection. All Rhima’s machines have a “thermo stop” which means the cycle will not complete if the temperature has not reached the safe minimum for sanitation. Cycle times may be longer. For machines connected to cold water if possible connect to 3-phase power supply.

    Does my machine comply with HACCP guidelines?

    Rhima has developed a unique monitoring program that takes safety, hygiene and operational conditions into account. Once correctly setup your machine will comply with HACCP guidelines. At least once per year we recommend to do a safety hygiene test on the dishwasher. Rhima technicians are specially trained in carrying out preventative maintenance and HACCP testing on Rhima equipment. This includes temperature checks with a calibrated thermometer, residual protein swabs (before and after) as well as full preventative maintenance on the machine.

    Can I wash other items in glasswashers (eg, cups and saucers)?

    Yes other items such as plates, cups and saucers can be washed in glasswashers. Rhima glasswashers use the same washing technology as our larger dishwashers. You can wash cups, saucers and lightly soiled plates. It is not recommended to wash dinnerplates. If your glasswasher has been set up with our High Sparkle system then we recommend use for glasses only.

    The Optima range has a clean cycle which means the rinse water is saved for the next wash which allows mixed loads.
