BTU is leaking water from the inside. - Sanyo 09KHS51 Ductless Mini Split Air Conditioner

first check and make sure the inside blower is running if so check to make sure the filter is clean if that's not if it may be low on Freon charge or the evap coil is dirty.

Water in the heating chamber will cause your heater to make these sounds. If your water is cold, it will create condensation inside of the heating chamber. Another way water would get into the heating chamber is if your heat exchangers are leaking. Id check to make sure that heating chamber is not full of water, if theres any real accumulation of water, 2" or more, inside that chamber, the exchanger needs replacing. Otherwise, it sounds like condensation.

unit may be tilted towards front should be tiped back lift the bottom front of inside unit maybe.....

When the air gets cooled it also gets dehumidified, on the inside unit there should be a condensate drain. Check the drain to see if its clogged, also check to see there is a drain, I have seen units installed by "pros" who have forgot to intall it

Best thing is to replace it as it might be rusted inside in the bottom

Air conditioners take the moisture out of the air. When the air passes through the coils on the evaporator, they are cold. This causes the air to condense and water to form on the coils. It then drips off into a pan. When the pan is full if it is not drained, you will have an overflow and things get wet. How much water the unit collects depends on how much humidity is in the air, how much air you are moving through the coils and the temp of the coils.

It sounds like your water has either been running at a low pH level, or you have a salt system. Basically your heat exchanger coil has dissolved into your pool water.
The exchanger can be replaced although it is pricey. I would recommend replacing it with a cupronickel coil. This is far more resistant to the type of corrosion you have experienced. Just be sure to keep a closer eye on the pH also.

You're supposed to hear water inside it. That shows that it is removing the humidity from the air. If it is leaking into the room, tile the outermost end down about 1/2" lower than the inside end.

It is very frail if you bump the heater hard while it is hot or cold you can crack it. If you have any water leak inside the heater or a condensation problem that drips water on it while it is hot this will break it every time.

Your by-pass assembly may have been damaged and is causing the water to overheat inside the heater causing the clanging. To fix this you will need to break down the water supply side of the heater and replace the bad parts. good luck and I hope this helps.
