Fault Nb. 8 - Flow Switch - No Water Malfunction
Description : Fault related to the Flow Switch located at the output of the feed water pump (Speck Pump). After the
pump is activated, the pump flow is controlled by the flow switch. If the flow switch does not feel the passage of
water within the specified time, the device switches off with fault number 8.

Solution :
* There may be no water left in the condensate tank.
* At the outlet of the condensate tank, the strainer on the pump suction line may be clogged, it must be cleaned.
* Make sure that the pressurization pump supplies water.
* The feed pump may not supply water. Speck pump check valves can be contaminated, it should be cleaned.
* If water is normally coming from the pump outlet but the device is failing, the flow switch must be structurally
controlled. Remove the union on the middle part of the flow switch and check whether the flow flap sensor of the
flow switch moves freely.
* When the captor is moved in the direction of the arrow in the upper direction, it must return to the same position
automatically. If not, the internal spring mechanism is damaged and the flow switch must be replaced.
