[What to do in such troublesome bathroom situations] The water doesn't heat up to the set temperature even after heating, the water level is unstable, the reheating function doesn't work, or an error message appears. Before considering the inspection and repair of your water heater, please also check the filter and filter guide, which are components of the bathtub circulation fitting. The filter and filter guide are important parts that are closely related to the circulation of hot water, in addition to reducing debris and scum entering the pipes. They are used in various bathtubs, such as those in detached houses, apartments, and condominiums. [How to remove the filter guide] Gently pull the fixing pin to make the head protrude. Pull the center knob with pliers, etc. Then, turn the filter guide to remove it. *In the case of a fixing pin, be careful not to completely remove the pin. After replacement, make sure it is securely fixed; if it comes off easily when pulled, reattach it. Incorrect installation can cause poor water flow and various malfunctions. *Shapes may vary depending on the series (some may be fixed with + screws, etc.). [Filters and guides come in a wide variety of sizes and shapes depending on the manufacturer and series] Product-specific names and part numbers are generally not stamped on the parts themselves. You will need to remove the filter and guide you are using and check the shape and dimensions yourself. I am selling this because the size did not fit. Thank you for looking.
