Step one should always be to turn off the washing machine, unplug it from the mains and turn off the taps.
Water pool in front/back of the machine
Something must be wrong with the water supply hoses. Check if they are properly connected. If the hoses are brittle or corroded with rust, replace them.
Rust and mineral deposit inside
Probably the drain hoses are responsible. These attach with spring clamps, which can loosen. Check if they are secured properly in the drainpipe and aren’t clogged up. Brand new washing machines come with a drain plug: don’t forget to remove it before you hook up the drain hose.
Leak in front of the cabinet
It’s all about the water pump. It has several seals that can tear or break. Look for a possible leak where the pump’s drive shaft enters the pump casing.
Water drips or beads near the seals
The seals on the air dome and the tub can become brittle with age that could lead to leaking water. On front-load washers, check for moisture around the outside of the door seal.
Excess foam overflow during wash cycle
Overdosing might occur if you use too much laundry detergent. Choose a good detergent that cleans well while removing stains effectively, so you don’t feel the urge to overdose even in case of very dirty garments: choose Ariel Automatic Power Gel Original.
Always be sure that the door is closed properly. Watch out for reasons that could stop it from closing: clothes stuck in there; dirt build-up around the seal; the machine not sitting level on the ground; or use of too much or the wrong detergent for your laundry. Check the list!
Leaking water under the machine
These are often caused by a hole in the water pump or leaky internal hoses.
It is better to turn to a professional if the leak occurs regularly despite your efforts. So keep the number of a local washing machine repair man at hand for emergencies.
