My MrCool is leaking water inside. What can I do to fix it?

When your MrCool DIY ductless mini-split system starts leaking water inside your home from the wall cassette, you can follow a systematic repair process. First, shut off the system immediately at the circuit breaker to prevent electrical hazards and stop condensation generation. Second, remove the front plastic cover and take out the washable mesh air filters to check for heavy dust buildup that could be freezing the coil. Third, check the internal plastic drain pan and locate the flexible condensate drain hose to see if algae slime has blocked the exit port. Fourth, clear any clogs in the drain line using a shop vacuum or by flushing with warm vinegar water. You can troubleshoot drainage flow easily. You can verify that your fix was successful when turning the power back on and running the AC results in clear, unimpeded water flow outside without indoor leaks.
