The short version
When the BDFB line stops cleaning properly the cause is usually flow rather than heat. The platform relies on both spray arms turning, and anything that blocks a jet or stops an arm waters one sector of the machine and nothing else. Load the machine, then spin both arms by hand before suspecting anything electrical.
What you will notice
- Dried-on deposits reappear after a good clean — For the models in the table on this page, debris that returns within a cycle or two points at the filter stack, since water is being recirculated through whatever the mesh failed to hold.
- The lower spray arm will not turn by hand — Something is catching it, and an arm that cannot turn sprays one direction only while the machine sounds entirely normal.
- Detergent is left in the dispenser at the end of the cycle — Undissolved detergent means the dispenser did not open, the water was cold, or the tablet was blocked by a dish immediately in front of it. That holds across every model this page covers.
- NEAR MISS: the machine does not run at all — A no-start fault, covered by the will-not-start page for this family.
What is usually behind it
- A blocked or partly blocked filter stack — First on the BDFB line because both spray arms are fed through it: a mesh that is three quarters full reduces flow to every jet at once, so the whole machine washes weakly rather than one part failing. It does not vary across the models listed on this page.
- Loading that shields the load from spray — Second and entirely free to fix. A tray across the lower rack, nested bowls, or a handle stopping the upper arm each remove a whole sector from the wash while the machine runs perfectly. It is the same on all the models in the table on this page.
- Scale on the heater and the jets in a hard-water area — Scale narrows every jet and insulates the element, so a machine in a hard-water district declines steadily even when the filters are kept clean.
- Detergent stored badly or past its usable life — Tablets absorb moisture and stop dissolving properly, which produces a machine that washes with plain hot water and no chemistry at all.
- A wash pump losing pressure — Last because it is indistinguishable from a restriction without dismantling: both give weak spray from healthy-looking arms, and everything upstream is free to exclude first.
How to narrow it down
- Load the machine, then spin both spray arms by hand — First because it is free and because an arm that strikes an item is the whole fault surprisingly often on the BDFB line. The same is true of each model covered here.
- Unscrew and wash the filter stack — Second because both arms are fed through it, so it is the one component that degrades the entire wash at once rather than one sector.
- Hold each arm up to the light and check every jet — Third: a plugged hole is visible immediately and clears with a cocktail stick and a rinse, and it explains a band of dirty items with clean ones either side. Every model in this family behaves this way.
- Compare a short programme with a long one — Short cycles assume lightly soiled loads. If a long hot programme cleans and a short one does not, nothing is broken and the programme choice is the answer.
- Note which items are dirty and where they sat — A repeatable position is a flow shadow, and moving the same item elsewhere for one load proves it in a single cycle.
Working safely
Safety
Isolate the appliance at the breaker before anything is dismantled. The heating element and the tub base stay hot for some time after a programme, so let the machine cool before reaching into the sump or handling the lower spray arm.

When to book a visit
The line on these models is simple: everything that affects flow is reachable from inside the tub, and everything that generates flow or heat is not. Call when you have exhausted the first group, and call immediately if the machine trips its breaker on a hot cycle. The models in the table behave the same way here.
