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 Montpellier fault codes that point at this
A Montpellier 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:
- F00 — The dishwasher has decided there is too much water inside it, so it has stopped the cycle to avoid a flood.
- F01 — The dishwasher thinks water is escaping where it shouldn't, so it has shut the cycle down and is trying to pump itself dry.
- F02 — The dishwasher can see water still flowing into it at a moment when the water valve is supposed to be shut, so it stops rather than risk overfilling.
- F04 — The dishwasher tried to fill but the flow meter — the little sensor that counts water going in — reported nothing arriving, so the machine stopped rather than run dry.
- F05 — The dishwasher isn't getting the water it expects, or the water it did take in has drained away again, so it stops the programme and flags F05.
- F06 — The dishwasher has decided the water in the tub has got too hot — or that the sensor reading that temperature can no longer be trusted — so it has abandoned the programme.
- SE — The dishwasher's control board has found that its own stored settings no longer add up, so it has stopped rather than run a cycle it can't trust.
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 Montpellier 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
- 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

Common questions
Why is my Montpellier 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 Montpellier 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 Montpellier error codes mean not draining?
Montpellier dishwashers report this through their own fault codes. The ones that point at not draining are F00, F01, F02, F04, F05, F06. If your machine is showing one of those, that narrows it down considerably — each has its own guide on this site.
