Could it be loose or perished fill hose?

Feel the hose connections at the back with the water on. Rubber fill hoses should be replaced roughly every five years. Tighten the connection or fit new hoses — braided stainless ones are worth the small extra cost. Typical cost: DIY.

Could it be damaged door seal (front loaders)?

Fold back the rubber boot and look for tears, trapped debris and mould along the lower edge. Clean it, or replace the boot if it is split. Typical cost: $200–$420.

Could it be leaking drain pump or its housing?

Water only appears during the drain part of the cycle. Replace the pump or reseat the housing. Typical cost: $180–$390.

Could it be overdosed detergent?

Excess suds overflow the tub, which reads as a leak. Common in soft-water areas where far less detergent is needed. Use the correct dose for the machine type and your water — high-efficiency machines need much less than people expect. Typical cost: DIY.

Washer Leaking From Bottom

Where the water appears tells you the cause: leaks at the back are usually hose connections, leaks at the front on a front loader are usually the door seal, and a leak only during drain points at the pump or drain hose.

Before you start: Switch off power and the water supply before investigating, and mop up promptly — a slow leak under a machine damages flooring fast.

When to call a technician

Any leak you cannot trace to a hose or the door seal should be looked at before it reaches the subfloor.
