I can see drips in the washing machine while it is not in use. Is that normal or is it a sign for water damage?
Consider installing a single-handled valve that makes it easier to turn off the water supply to the washing machine The washing machine is connected to both cold and hot water lines. Check both water lines. Check the filters and clean or replace them periodically. A slow flow problem is more common in areas with "hard water" (water that has a lot of minerals, such as calcium, magnesium, and salts, dissolved in it from the rocks and earth in the area that the water is collected).
A clogged filter slows the water flow into the washing machine, causing it to sometimes malfunction. If you detect a leak, replace the valve. Start with the connections and fix every leak you find immediately. Be sure to check both ends of the water lines for possible leaks. Inspect the shut off valve by looking for drips into the washing machine while it is not in use.
Hoses & Filters
Do not ignore the discharge hose. When replacing hoses, be sure to install new hose washers and consider installing longer-living steel-braided hoses. Like with most appliances, washing machine problems often originate in the hoses. Periodically check these hoses and replace them if brittle or old. Preferably, there should be at least 4 inches of clearance between the water connection and the back of the washing machine. This space will help reduce the chances that the hose will kink and burst. When inspecting, search for kinks and cracks
The dryer is connected to a ventilation hose. Check it carefully. Search for lint accumulation behind and under the dryer and make sure the vent pipe is not clogged and that it is debris-free. Make the exhaust route as short and straight as possible for the dryer to vent efficiently The dryer ventilation hose must be connected to the outdoors.
The utility sink is sometimes the source for water-related problems. Then, look around the sink; slow draining pipes may indicate a partially blocked drain. Start by searching for leaks under the sink. Replace sink seals if they are cracked or loose. A constantly dripping faucet must me repaired right away. Damp, soft, or stained walls and floors around plumbing pipes indicate an internal leak that must be fixed before additional damage occurs A drip in the trap under the sink can be a sign for drain problems and should be repaired immediately.
