A3 Indoor Malfunction of drain Level control system

you got a problem with the drain. The pump is running too long and the float isn't dropping down within time..

[yacoub]

what should i do to solve that problem ?
thanks

call an engineer?

[a/c.king]

youve got faulty floating switch,sensor etc......

cassette lift pumps on daikins run constantly when in cooling mode and for 1 minute afterwards, either slime /crap in ur drip tray or the drain off the unit is blocked- on the outside of the cassette remove the jubilee clip on the drain - see if it pumps into a bucket, then if this is ok, blow down the drain pipe you disconnected- it may be healthier using compressed air butit gives you a few pointers to check, if the drain is clear and the condensate pump shifts water then the hi lmit float switch may be stuck/jammed- or as a last resort unplug the float plug off the pcb, in uk its a yellow 2 core wire, test continuity on the plug- i have had a float switch fail when all is ok.

yes, the pump is always running ,
