From where the evaporator or condenser unit. If it is from your evaporator the unit might need service coil might be dirty or the drain hose is clogged

I have MS-A18VD Mitshubishu air-conditioners since 3 years. One of them now leaves over the full width brown sticky drops, where the air flows out. The other ones don't have this. It looks like there...


brown liquid usually is rust, could be from the a/c or the heater block you would need to investigate further to determine the liquid, is there any water lose, is a/c pressure still ok, if you have not had the a/c checked in 3 years I would have it checked.

Mr Slim is dripping condensation into the room. I use this to heat and cool a 500 sq ft finished space over garage. I have been looking for troubleshooting guides but no luck. It is cooling the space,...


Hi,

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

Wash blinks H F


FH_ This will occur when No water is detected entering the machine or The pressure switch trip not detected.

If after 30 seconds the control does not detect water entering machine, the valves will be turned off and the error code will be displayed.
OR
If the control has turned the water valves on, and after 8 minutes, the flow sensor has detected 10.5 gallons of water passing through it, but has not detected the pressure switch trip, the valves will be turned off, and the error code will flash.

Press PAUSE/CANCEL twice to clear the display.

Possible Causes / Procedure

• If there is no water in the unit:
- Make sure that both valves at the water source(s) are turned on all the way.
- Check for plugged or kinked inlet hoses or plugged screens in the inlet valves.
- Verify inlet valve operation.

• If there is water in the unit:
- Verify drain pump operation.
- Verify that the pressure switch hose is in good condition and properly connected to tub
and pressure switch.

1. Verify there is not a siphon problem.
2. Unplug washer or disconnect power.
3. Verify wire harness connections to inlet valves, pressure switch, drain pump, flow meter,
and Central Control Unit (CCU).
4. Check all hoses for possible leaks.
5. Plug in washer or reconnect power.
6. Verify pressure switch operation.
7. Verify flow meter operation by blowing air through the part and measuring the resistance.
8. Verify CCU operation by running a Diagnostic test or any cycle.

Replace failed component.(Which will be the CCU, if the pressure switch and hose are operational. Follow the procedure below to confirm optimal pressure switch function)


HI, the water level switch(aka pressure switch), is responsible for regulating the water fill level in this situation. It does this through a plastic tube which runs from the switch in the control console down to the side of the outer tub, near the bottom . The tube is filled with air. As water enters the tub it also enters the tube. As water climbs inside the tube, it pushes on the air trapped inside and increases the air pressure. When the air pressure reaches a certain level, it triggers the switch.

I would advise to Inspect the air tube for kinks, breaks or damage. The tube should also be free of water. The tubing should be securely connected to the bottom of the outer tub and to the bottom of the water level switch. If there is water present, the switch must be replaced.

The water level switch has three connectors. Label and disconnect the wires from the switch. Test the switch for continuity using a multimeter. Set the multimeter to the ohms setting X1. It will be necessary to test each of the three possible pairs. replace the switch if it fails the continuity test.
