New World dishwasher not draining

What is actually happening

A dishwasher drains through a filter, a pump, and then a hose that usually loops up and into the sink waste. Standing water almost always means a blockage in that path rather than a failed part — food debris in the filter and a blocked sink trap between them account for most of it. The one to check first is whether a new sink or waste disposal has been fitted, because the blanking plug in a new waste spigot is a classic.

The New World fault codes that point at this

A New World dishwasher will usually tell you what it thinks is wrong before anyone opens it up. These are the codes we hold for this make that relate to not draining:

• F01 — The dishwasher has tried to pump the water out, given it three minutes and the water level hasn't dropped, so it has stopped and flagged a drain fault.
• F03 — The dishwasher has spotted water still flowing into the machine when the fill valve should be shut, so it has stopped the programme rather than risk overfilling.

If yours is showing one of those, that is a much shorter conversation than a general fault — tell us the code when you book and the engineer can often carry the part.

The usual causes on a New World dishwasher

• A clogged filter and sump at the bottom of the machine
• A blocked or kinked drain hose, or a blocked sink trap where it connects
• A blanking plug left in the sink waste spigot after a new sink or disposal unit was fitted
• A failed drain pump, or one jammed with a piece of glass or a label
• A drain hose fitted without a high loop, letting waste water siphon back

What you can safely check yourself

1. Bail out the standing water, then lift out the filter assembly and clean it thoroughly
2. Check the sump underneath the filter for glass, labels and debris
3. Check the sink trap the dishwasher drains into — clearing that alone fixes a good share of these
4. If a sink or waste disposal was fitted recently, check the blanking plug was knocked out of the spigot

Common questions

Why is my New World dishwasher not draining?

The cycle ends with dirty water standing in the bottom of the machine. A dishwasher drains through a filter, a pump, and then a hose that usually loops up and into the sink waste. Standing water almost always means a blockage in that path rather than a failed part — food debris in the filter and a blocked sink trap between them account for most of it. The one to check first is whether a new sink or waste disposal has been fitted, because the blanking plug in a new waste spigot is a classic.

Can I fix a New World dishwasher not draining myself?

Bail out the standing water, then lift out the filter assembly and clean it thoroughly. Check the sump underneath the filter for glass, labels and debris. Check the sink trap the dishwasher drains into — clearing that alone fixes a good share of these. If a sink or waste disposal was fitted recently, check the blanking plug was knocked out of the spigot. Those checks fix it more often than not.

What New World error codes mean not draining?

New World dishwashers report this through their own fault codes. The ones that point at not draining are F01, F03. If your machine is showing one of those, that narrows it down considerably — each has its own guide on this site.
