Programme III (Intensive hot programme)
The glasses are cleaned with a rinsing temperature of 60°C. The final rinse is then
carried out with fresh water heated to 65°C. The described extension of the running
time also ensures that the required temperatures are reached in Programme III.
Caution
Glass corrosion and loss of decorations due to high water temperatures and
long wash cycle times
•
Make sure that the dishes and glassware used are suitable for the high stress
placed on them.
MEIKO offers two types of machine with thermal disinfection for institutions with ad-
ditional hygiene requirements. Both versions have greater heating performance in
the wash tank than standard machines.

The term A refers to a way of measuring how microorganisms are eliminated by

moist heat disinfection methods. By using a moist heat disinfection method, it is ex-
pected that a specific temperature over a period of time has the effect of eliminating
a predictable number of microorganisms with a particular resistance.
The standard setting for a dishwasher with A
•
The tank temperature during washing is up to 74° C.
•
For tank temperatures of 65° C or higher, each tank temperature is assigned a
factor.
•
Using the measured tank temperature, a value is determined and added every
second until the hygiene value A
•
The rinsing process runs until the end of the programme cycle time, but at least
until the temperature value is reached. After this comes a pause for draining
and the final rinse.

Thermolabel control
In a way which is similar to A
disinfection process which uses moist heat. The dishwasher heats the rinse water to
a higher temperature in order to eliminate germs. The efficacy of the disinfection can
be tested using a measurement strip, the Thermolabel. The measurement strip
changes colour after 4 seconds at 71 °C for a wash item.
•
During washing, the tank temperature is heated up to 71° C and maintained at
that temperature.
•
The rinsing process runs until the end of the programme cycle time, but at least
until the temperature value is reached. After this comes a pause for draining
and the final rinse.
•
Washing at high temperatures and long spells in the wash tank can lead to
glass corrosion and premature wear to decoration.
