A cracked or weeping washing machine inlet hose can quietly cause serious water damage in a home, holiday rental, or hotel laundry room before anyone notices. The video above walks through the full swap visually; this article breaks it down into clear steps you can follow with basic tools and a replacement hose from any hardware store in Greece. Done carefully, the whole job takes under thirty minutes and requires no special plumbing skills.
Why Inlet Hoses Fail
Most washing machines come with standard rubber inlet hoses that degrade over time due to water pressure, heat cycles, and UV exposure — a particular concern in sun-drenched Greek properties where utility rooms can get warm. The rubber stiffens, develops micro-cracks near the fittings, and eventually leaks or bursts.
Braided stainless-steel hoses are the upgrade worth making at replacement time. They resist pressure spikes and last significantly longer than plain rubber, making them ideal for holiday rentals or managed properties where a slow leak can go unnoticed between guest stays.
What You Will Need
Pick up a pair of replacement inlet hoses (hot and cold, or a combined cold-only set depending on your machine) in the same length as the originals — typically 1.5 m. You will also need an adjustable spanner or pliers, a small bucket or towel, and PTFE thread-seal tape. Some hoses come with new rubber washers at the fittings; if not, buy a packet separately as old washers are the most common source of drips after a hose swap.
How to Replace a Washing Machine Inlet Hose
- 1
Turn off the water supply and unplug the machine
Locate the isolation valve or stopcock behind or beside the machine and turn it fully clockwise to shut off the water. If there is no dedicated valve, use the main supply valve for that room. Unplug the machine from the wall socket — never work on a connected appliance. Pull the machine gently forward to give yourself comfortable access to the back.
- 2
Drain the existing hose
Place a small bucket or folded towel under the hose connection at the wall valve. Using an adjustable spanner, loosen the coupling nut at the wall end first, turning anti-clockwise. Water trapped in the hose will trickle out — let it drain fully before removing the other end at the machine's inlet port. Keep the bucket handy as you pull the hose free.
- 3
Inspect the inlet port and remove the old washer
Once the hose is off, look inside the threaded inlet port on the machine and at the wall valve fitting. Extract the old rubber washer with a fingernail or flat screwdriver. Check the threads on both fittings for limescale or corrosion — a short scrub with a damp cloth and an old toothbrush cleans them up. In hard-water areas common in Greece, a descaling spray can help here.
- 4
Fit the new hose with fresh washers
Drop a new rubber washer into each end fitting of the replacement hose. Hand-tighten the machine end first, then the wall valve end. Once finger-tight, use the spanner to snug each coupling a further half-turn — firm but not over-tightened, as excess force can crack plastic inlet ports. If the thread feels rough or cross-threaded, back off and re-seat it rather than forcing it.
- 5
Restore water, check for leaks, and push the machine back
Slowly open the isolation valve and watch both fittings for ten seconds. A drip means the washer is not seated correctly — tighten by another quarter-turn maximum. Run a short rinse cycle and inspect the connections again while the machine fills. Once confirmed dry, push the machine back into position, making sure the hose is not kinked or pinched behind the appliance.

FAQ
- How often should washing machine inlet hoses be replaced?
- Rubber hoses should be replaced every five years as a precaution, or immediately if you spot any bulging, cracking, or moisture around the fittings. For rental properties or hotels, checking hoses at each seasonal service is a good habit. Upgrading to braided stainless-steel hoses extends the safe interval considerably.
- Can I use the same hose for both hot and cold inlets?
- Only if your machine has a cold-fill-only design, which is common in modern European washing machines including most models sold in Greece. Check your appliance manual: if there is a single blue inlet port, one cold hose is all you need. Older or American-style machines have separate hot and cold inlets and require two hoses.
- The coupling feels very stiff — should I use force or a longer spanner?
- Avoid excessive force on plastic inlet ports as they can crack. Instead, apply a penetrating spray to the old fitting threads and wait five minutes before trying again. If the coupling is seized due to limescale, a descaler solution soaked around the joint for ten minutes usually frees it. Once loose, finish removal by hand to keep control.
