What to do if the WDT Control Unit shows a minimum pressure alarm?
- R
  Rodney WillisAug 4, 2025
  If the WDT Control Unit displays a minimum pressure alarm, it means the pressure switch on the booster pump is reporting insufficient flow pressure. This could be due to several reasons. First, check if the supply pressure is too low. Secondly, inspect the booster pump for any faults. Also, the pressure switch itself might be faulty. Check the pressure switch. You can also set a lower response pressure at the pressure switch.

How to fix a 'suct. pipe ALARM' on a WDT Control Unit?
- A
  Amanda WhiteAug 9, 2025
  If your WDT Control Unit displays a 'suct. pipe ALARM' (flow), it indicates that the water flow in the suction pipe is too low. The switch body of the flow switch does not rise, the switch LED lights up. Here's what you can do: * Check the booster pump functioning. * Clean the dirt filter, as it may be contaminated. * Ensure there isn't a blocked suction opening in the flushing tub. * Check for particles in the injector’s nozzle or in the suction pipe. * Insert a hole washer with a larger drill hole or remove it entirely. * Check for a blocked non-return valve in the dosing line. * Replace the diffuser nozzle if it is worn out (if D > 6.5mm).

What to do if WDT Control Unit shows 'Level max ALARM'?
- L
  Lee LarsonAug 14, 2025
  If the WDT Control Unit shows a 'Level max ALARM', it means the water level in the flushing tub is too high. If the injector's suction capacity is OK, check the floating valve function: The water inlet should gently follow the float’s movement. If this is not the case, insert a new diaphragm in the floating valve. If the suction capacity is not sufficient, see under fault display “suct. pipe ALARM”.

  If you receive a “Chlorine empty” notification on your WDT Control Unit, it means the “Chlorine empty” sensor has been triggered. You can refill the chlorine or change the container. If the dosing hopper is not empty, recalibrate the empty switch. It may also be necessary to renew and calibrate the empty switch.

What to do if the WDT Control Unit displays a 'pH empty' notification?

  If the WDT Control Unit displays a 'pH empty' notification, it indicates that the “Acid empty” sensor has been triggered. Replace the empty acid container with a full one. If the acid container is not empty, the empty switch is faulty. If the suction lance is new, check the float’s functional direction; the float should be at the bottom when empty.

Why does my WDT Control Unit show a 'Level min ALARM' for the flushing tub?
- M
  Michael RodriguezAug 29, 2025
  The 'Level min ALARM' on your WDT Control Unit indicates that the water level in the flushing tub is low. Ensure the floating valve is functioning correctly, the water inlet should gently follow the float’s movement. If OK, calibrate the water level. If not, insert a new diaphragm in the floating valve. You might also insert a hole washer with a smaller drill hole. Also, check if the dirt filter is contaminated and clean it if necessary.
