Question about Mitsubishi MSY-A15NA Split System Air Conditioner
Firstly i would try and establish if the unit is on a gravity drain or a pumped drain.
1. If the drain is gravity it means the condensate water will flow with gravity normally straight through the wall, so check for blockages outside and inside, the unit may look clean but if it hasn't been serviced there may be a build up of dirt in the drain.
So try and locate the outlet of the drain outside (normally by the refrigeration pipework to condenser) and attach a wet hoover to it and make a good seal, this will **** any water/dirt out of the drain line.
2.If its on a pump, a small water pump which collects the condensate in a sump and then pumps it away when a float is activated. (Normally fitted if a gravity drain option is unavailable).
You can check to see if the sump is full and overflowing which is an indication the pump/float has failed and will req replacing by an A/C company. Or the PVC drain line is blocked with dirt.
The pump is either located behind the unit in the casing, or in the white trunk containing the refrigeration pipework
All the best
