Step-by-Step Fix
Safety & Preparation
Before beginning any repair, ensure you have isolated power or water supplies. Clear your workspace, gather standard hand tools, and wear appropriate personal protective equipment (PPE).
- Locate the isolation taps or stopcock for your washing machine's water supply, usually found behind the appliance or under the sink. Turn these taps fully clockwise until they are completely closed to shut off the water flow.
- Carefully inspect the hose connections at both the washing machine and the wall or under-sink tap. Use an adjustable spanner or a pair of pliers to gently tighten any connections that feel loose, ensuring they are snug but not overtightened.
- Unscrew the hose from both the washing machine and the water supply tap to expose the rubber washers inside each end of the connection. Check these washers for any signs of wear, cracking, flattening, or damage; if they appear compromised, they will need replacing.
- Thoroughly examine the entire length of the hose itself for any visible cracks, splits, bulges, or soft spots that could indicate internal damage. If you find any such damage, the hose is compromised and must be replaced entirely.
- When fitting a new hose or reattaching an existing one, always ensure that new, undamaged rubber washers are correctly seated within each end of the hose connection. Hand-tighten the connections first, then use a spanner or pliers to tighten them an additional quarter to half turn, creating a secure, watertight seal without overtightening.
- Once the hose is securely connected, slowly open the water supply taps by turning them anti-clockwise until fully open. Carefully observe all hose connections and the length of the hose for any drips or signs of a leak before leaving the area.
