Using the dishwasher
1. Booster pump – pumps water from the break tank via the booster heater
to the rinse pipes for final rinse, as well as water from the break tank to the
hood lifting cylinder. It is controlled using solenoid valves.
2. Chemical wash pump – pumps water from the tank to the rinse pipes for
potwash (not with granules).
3. Granule pump – pumps water and granules from the granule part of the
tank into the rinse pipes for potwash.
4. Normal wash pump – pumps water from the tank to the rinse pipes for
normal wash.
5. Booster heater – heats the water which comes from the break tank for
pumping to the rinse pipes for final rinse.
6. Reversing valve – releases water to the rinse pipes for potwash, either
from the chemical wash pump or from the granule pump.
7. Pressure switch for the anti-crushing system – detects when water
pressure in the pipes to the hood lifting cylinder exceeds a set value (can
be adjusted by a service engineer). If the pressure exceeds this value, the
hood opens.
8. Inductive sensor – indicates if the rotating table is turning or not.
9. Flow meter – measures how much water is being pumped into the
dishwasher from the break tank.
10. Solenoid valve (two items) – these solenoid valves open to release water
to rinse pipes for final rinse and to the hood lifting cylinder.

path of the hood as it goes up and down.
19. Limit switch for hood carriage – indicates when the hood is in the closed
position.
20. Tank element – heats the water in the tank to the correct temperature.
21. Electrical connection - this is where the electrical cable is connected. The

nection.
