The following are things you can do if you notice that your Mitsubishi Mr. Slim is leaking water:

Step 1: Take Off The Filter And Cover

First, ensure that your air conditioner is turned off before attempting to carry out any do-it-yourself fix. Next, pull the front panel from the unit and take out the filters. If the filter is already dirty, you should either vacuum it or wipe away any dust on it.

Most mini-splits come with a front panel that can be removed quickly and easily by undoing a pair of screws. You will need a screwdriver to take them out. Next, try removing the protective cover made of plastic. Keep this somewhere secure while you work.

Step 2: Check For The Drainage Pipe 

There are usually two plastic clips located inside the air conditioner. If you press the clips, you can lift up the unit base. This will make you gain access to the pipe. The drainage pipe is big and is usually sealed using grip tape.

Step 3: Drain The Pipe

The next step is to disconnect the connection that is holding the drainage pipe together. Have a bucket ready to collect any water that will spill out. Once you have your bucket in place, disconnect the connection and let the water drain from both sides of the pipe.

Step 4: Clean The Pipe

As soon as the water stops draining from the pipe, use the hose of your vacuum to clean the excess dirt out of the pipes.

You can use a wet vac since the clog will be wet. Continue to vacuum until the obstruction has been eliminated. Apply electrical tape on the joint. After doing all these, put your unit back together as it was before.

Why Is My Mitsubishi Mr. Slim Leaking Water?

Here are possible reasons why your Mitsubishi Mr. Slim is leaking water:

Clogged Drain Pipe

Your Mitsubishi Mr. Slim could be leaking water for a variety of reasons, the most common of which is likely a clogged drain pipe. However, there are other potential causes as well.

While your system is on, the coil located inside the inside unit extracts moisture from the surrounding air. The drain line, which is also referred to as the condensate line, is responsible for carrying the water collected in the drain pan from the indoor unit to the outdoor unit. 

In the event that the drain line becomes clogged, it will no longer be able to drain the water into the exterior of the building. The water eventually starts dripping inside the home since there is nowhere else for it to go.

Overflowing Drain Tray

In addition to blocked drain lines, the air conditioning unit's drain tray may be overflowing. This plastic tray works by collecting any condensate that flows out of the unit. However, if it is not drained on a regular basis, it may become full and overflow. 

The problem can be easily fixed by removing the condensation tray from within the unit, emptying it, and then cleaning it before putting it back.

Damaged Drain Pan

A damaged drain pan is another possible reason why a Mitsubishi Mr. Slim leaks water. Drain pans are susceptible to a variety of damage, including the formation of rust over time or shattering when they are dropped.

Any damage to the drain pan will likely cause any water that is contained within it to leak out. This is because the drain pan stores moisture that condenses out of the air in your home.

If your drain pan is damaged in any way, then you will need to hire a professional to replace the component to get your system back to its normal functioning state.

Clogged Air Filter

A dirty air filter could also be the causes of your leaking. When an air filter is allowed to become overly soiled, dust and dirt may accumulate on the coils of the indoor unit.

As a result of this, the airflow throughout the system decreases, and there is a possibility that the coils could freeze. When the freezer coils return to their normal temperature, the frost and ice melt, and the melted water will trickle down your wall.

Make sure that the air filter on your unit is regularly changed in accordance with the instructions provided in the manual to prevent these kind of leaks.

Can I Use Mitsubishi Mr. Slim When Water Is Leaking?

No, it is recommended that you stop using your air conditioner when it starts leaking. Doing so is vital, even if you don't notice any difference in the air quality within your home. The flow of water and leakage stops when the system is not in use.

Additionally, your air conditioner's susceptibility to additional harm increases in proportion to the amount of water that escapes from it.

Can A Leaking Mitsubishi Mr. Slim Cause A Fire?

Yes, a leaking air conditioner can cause fires. These fires are frequently caused by leaking air handlers, which then cause electrical equipment in the surrounding area to short circuit.

This happens when you don't maintain the AC drain lines or pay attention to them. As a result of this issue, the drain lines become clogged and the drainage pans become filled.

Condensation can drip onto electrical equipment located beneath, causing it to short-circuit and produce sparks that can easily ignite nearby insulation, wood, and other combustible materials. This is more likely to happen in smaller homes. A fire accident can be disastrous.

Is AC Water Harmful? 

No, AC water isn't harmful. The water that is discharged from the air conditioner is pure condensate water. AC water can be collected in a bucket outside the house in order to water plants or for other uses.

Note that it is not advisable to drink it because it contains substances that shouldn't be consumed. Since the water comes from the inside of your house, it likely carries dirt from your house. Dirt in the pipes and coils may also be found in it.

To Wrap Up

AC leaks should be fixed as soon as possible. If you notice that your Mitsubishi Mr. Slim is leaking water, this could be a result of a clogged drain pipe. To fix this problem, all you have to do is take off the filters and cover, check for the drainage pipe, then drain and clean the pipe.
