The short answer
On a compact Blomberg the likeliest sources are the door gasket and the fill hose connections, in that order, and both are visible without opening the machine. Water appearing only at the end of a cycle points at the drain path instead. The tub seal is rare, and it is the one that ends the machine.
What you observe
- Water at the front, under the door — A gasket leak drips at the lowest point of the opening while the drum turns.
- Water at the back as soon as the taps are on — Supply leaks do not wait for a cycle; they leak whenever there is pressure.
- Water only at the drain phase — A clamp or a split drain hose spills only when the pump is pushing.
- Suds on the floor as well as water — Over-dosed detergent overflows the dispenser and runs down the cabinet.
- NEAR MISS - a damp floor with no trickle — Condensation on a cold supply line in a warm closet looks exactly like a slow leak.
Causes, most likely first on this brand
- A torn or fouled door gasket — First on any front-loader, and more so here, where the gasket is small and the door is used as a hand-hold to drag the machine out. Debris in the fold holds the seal open; a tear at the bottom leaks only while water is thrown.
- Fill hose connections at the taps or the machine — Second, because they are the joints most often disturbed. A closet washer is pulled out for every filter clean and the hose ends take the strain. These are the leaks that flood floors, because they do not stop with the cycle.
- Detergent overdosing and dispenser overflow — Third, and easy to dismiss. A compact drum needs far less detergent than a full-size machine, and the excess foam pushes water past the dispenser and gasket.
- A drain hose or clamp that leaks under pump pressure — Fourth. The timing is the clue: nothing during fill or wash, water at the drain.
- A failed tub seal or cracked outer tub — Last, deliberately. It leaks from the centre of the base during the spin, it is not an owner fix, and on a compact washer it usually ends the machine.
Check in this order, and why
- Note which phase the water appears in — Fill, wash and drain each point at a different part of the machine.
- Dry the floor and run a short cycle with a torch — Watching the leak start answers in one cycle what guessing will not in three.
- Wipe right around inside the gasket fold — Debris and small tears are both found by hand.
- Check both ends of each fill hose with a dry tissue — A tissue finds a weep that a hand cannot.
What an owner can safely check
- Dry everything and identify the phase — Paper towel under the machine, then watch which phase wets it. This decides everything after.
Tools: paper towel, torchAbout 30 min
- Clean and inspect the door gasket — Open the fold all the way round, clear grit and hair, and look for splits at the bottom.
Tools: clothAbout 20 min
- Check and re-tighten the fill hose ends — Hand-tight plus a small turn, washers fitted. Replace a bulging or rust-stained hose rather than tightening harder.
Tools: adjustable wrench, dry tissueAbout 20 min
- Run a load at half the detergent dose — Use the dose for a compact drum, not the one printed for a full-size machine.
About 60 min
- STOP HERE if water comes from the centre of the base on spin — That is the tub seal.
Before you open anything
Safety
Switch the machine off at the breaker before mopping under or behind it - a wet closet floor and a live appliance deserve respect, and a capacitor can hold a charge after the power is off. Close both taps before disturbing a fill hose. If the machine trips a breaker or a residual current device while leaking, leave it off and call: water has already reached something electrical.
When to call a technician
Call when the gasket is clean and intact, the hoses dry, the dose right, and water still reaches the floor - particularly when it appears at the centre of the base during the spin. Call immediately, taps closed first, for any supply-side leak you cannot stop: that one does not end with the cycle.

What this page does not cover
This page describes the Blomberg compact front-load washers as a class, not a single model line; where a family-specific page exists it is linked below and is the more exact answer. Not here by design: gasket and seal part identifiers, hose thread sizes, detergent dose figures and tub capacities, which vary by family.
