Drainage & Blockages

Appliance Waste Blockage Clearance

Appliance waste blockage clearance resolves slow draining, overflows and bad smells from washing machine and dishwasher waste pipes. The service focuses on finding where the blockage sits, clearing it safely, and confirming the appliance drains properly again so you can get back to normal use with confidence.

More information

What appliance waste blockage clearance covers

If your washing machine or dishwasher is backing up, draining slowly or leaving unpleasant odours, this service is designed to restore safe, reliable drainage.

  • Investigation of likely blockage points: appliance hose, trap, under-sink pipework, external gully
  • Identification of common causes such as lint, grease, food debris, scale or pipework restrictions
  • Safe clearance using the most suitable method for the pipework and access
  • Checks for leaks, poor connections or damaged pipe sections affecting drainage
  • Confirmation of flow by running water through the waste and checking the outlet

When this service is most useful

You may need clearance if the appliance:

  • Leaves standing water or fails to pump out
  • Causes the sink to back up when it drains
  • Overflows from the standpipe or trap
  • Produces recurring odours, especially after use
  • Has repeated issues after DIY clearing attempts

This is also a practical call-out for landlords between tenancies and small premises where downtime needs to be kept to a minimum.

How the service is delivered

The visit typically starts with a few checks to narrow down the location and cause, then targeted clearance.

  • Isolate and protect the area before working on pipework
  • Trace the route from the appliance connection to the nearest accessible drainage point
  • Clear the blockage and remove contributing build-up where possible
  • Re-test drainage and confirm normal flow

If access is restricted or there is a deeper drainage fault, you will be talked through the options before any further work is carried out.

After clearance: reducing the chance of repeat blockages

Once flow is restored, you will get practical guidance on prevention. This may include simple maintenance steps, correct hose positioning, and advice on what not to put down the system to avoid future call-outs.

Frequently Asked Questions

What are the common signs of a washing machine or dishwasher waste blockage?
Typical signs include slow draining, standing water at the end of a cycle, gurgling noises, and bad smells. You may also see water backing up into the sink or overflowing from the waste connection.
Can I use chemical drain cleaners to clear the blockage?
They sometimes shift minor build-up but often fail on lint, grease or solid debris, and can damage seals and pipework. If chemicals have been used, mention it so the area can be handled safely.
Will the appliance need to be moved to clear the waste pipe?
Sometimes, yes, especially if the blockage is at the hose, trap or behind the unit. If moving is needed, it will be done carefully and only as far as access requires.
How long does appliance waste blockage clearance usually take?
Many blockages are cleared within a single visit, depending on access and how far along the waste line the restriction is. More complex issues may take longer if pipework needs adjustments or parts replacing.
Will the blockage come back after it has been cleared?
If the underlying cause is ongoing, such as repeated grease build-up, poor pipe fall or restricted fittings, it can return. You will be advised on prevention and, where needed, on repairs that make drainage more reliable.
