Error 7937 : “Waterflow”
No water flow detected. This error is not preceded with a warning.
Situation
Solution
Interruption of the liquid cooling
circuit.
Check if the loop of the liquid cooling circuit is closed.
Electrical disconnected flow switch
(ref F image 3-21).
Note: The FLM HD has no flow
switch.
Reconnect the wire unit (ref C image 3-21) of the flow switch.
No or insufficient liquid inside the
cooling circuit. The pump is sucking
air and sounds noisier then normal.
Fill the cooling circuit with liquid and expel all air. Pressurize the circuit. See chapter
"FLM liquid cooling circuit", page 153.
Malfunction pump. You don’t feel
any vibrations when touching the
pump after activating the “Refill
mode” via the user interface:

Yes
Note: to exit the “Refill mode” you
have to switch off the projector.
•
Clean the bearings of the cooling pump. See chapter "Maintaining the cooling
pump", page 190.
•
Replace the cooling pump. See procedure "Cooling pump body replacement",
page 194.
Tip: It’s not necessary to drain the cooling circuit of the light processor. Bypass this
part of the cooling circuit.
Defect flow switch. The pump is
functioning normally in the “Refill
mode” but the projector displays a
water flow error.
Note: The FLM HD has no flow
switch.
Drain the liquid cooling circuit, replace the flow switch, fill and pressurize the liquid
