In Japanese, air conditioners are called エアコン (“e-ah kon”) *e as in “egg”
Below are some common air conditioner remote controls and their English translations.
Your air conditioner filters should be cleaned at least once a month. They can usually be easily removed to be vacuumed or washed.
If you see mould growing inside your air conditioner in a hard to reach place, you will probably need to hire a professional cleaner (there are many companies available).
Hot Water Remote Control
Some apartments have wall-mounted remote controls for controlling hot water temperature, volume, etc. Usually there is one near the bathroom and one near the kitchen. The buttons will differ depending on the model, age of the remote control, and whether your water is heated by gas or electricity (gas is more common).
Apart from the basic buttons (start/stop and adjusting temperature), most of the features only concern filling up the bathtub with water (i.e. if you only take showers, you can usually ignore most of the buttons).
It is OK to leave your hot water remotes in “on/start” mode all the time.
The array of features and button layout can vary widely between machine models.
Some models come with a lid lock (ふたロック = futa rokku) where the lid cannot be opened mid-cycle, unless the cycle is paused.
Make sure to clean your washing machine drum at least once a month to prevent odour and mould growth. You can use a variety of products such as baking soda, oxygen bleach (such as OxiClean) or a specific washing machine cleaner.
Air drying features on washing machines do not completely dry clothes; they remove excess moisture so that clothes will dry faster in a dryer or outside.
Make sure to only fill a washing machine to about 70% capacity to avoid machine wobble and clothes tangling.
