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 washing 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. Some brand new washing machines come with a drain plug: don’t forget to remove it before you hook up the drain hose.
Excess foam overflow during wash cycle
Oversudsing might occur if you use too much laundry detergent. Choose a laundry detergent designed for washing machines that cleans perfectly while removing tough stains effectively. Refer to the dosage instructions on your laundry detergent pack: choose Ariel Power Gel.
Leaking water under the washing machine
These could be 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.
