Problem summary

Water pooling underneath your Beko washing machine, particularly at the start of the cycle, suggests a leak in one of several key components. You may also notice the drum sounds different during the spin, or the machine requires multiple button presses to start properly. These signs point to internal wear or failure in parts that cannot be safely repaired without specialist knowledge.

Likely causes

Based on 74 similar faults reported to SMC Services, the most common sources of leaks are:

Door seal (41%) — The rubber gasket around the drum door degrades over time, allowing water to escape during wash and spin cycles. Worn or misaligned seals are a frequent culprit in Beko freestanding models.

Heater element (20%) — The heating element sits in a sealed chamber. If it corrodes or fractures, water leaks into the electrical housing beneath the drum.

Motor or pump assembly (16%) — Mechanical wear or failed internal seals in the pump or motor unit can cause water to leak from connection points or housing joints.

Each of these is located in the appliance's inner workings and involves electrical components, sealed systems, or parts that require precise reassembly.

Why this needs an engineer

All three likely causes involve either sealed refrigeration or heating systems, electrical connections, or mechanical assemblies where improper diagnosis or repair can:

Create electrical hazards from water entering live circuits
Damage the appliance beyond economical repair if the wrong component is replaced
Void any remaining warranty if non-qualified work is attempted
Leave the leak unresolved, leading to water damage to floors and cabinets

Even if you can locate the leak visually, identifying which component has failed requires specialist diagnostic equipment and safe access to mains-powered parts.

When to call SMC Services

Contact a qualified engineer as soon as the leak is noticed. The longer the machine runs with active leakage, the greater the risk of electrical fault or structural damage. During the engineer's visit, they will:

Inspect the door seal, heater housing, and pump connections
Run the machine under controlled conditions to pinpoint the leak source
Replace the faulty component and test the repair thoroughly
Advise whether the appliance has suffered secondary damage

Note that the spin cycle sounding different may indicate mechanical strain related to the same fault, so mention this to the engineer when you book.

If you're in Northern Ireland, SMC Services can usually book a repair within 2-3 working days.

Step by step

Water visible underneath the machine during the wash cycle. Switch off the appliance immediately and unplug it from the mains socket. Do not attempt to run further cycles. This indicates an active leak from an internal component.
Spin cycle produces unusual noise alongside the leak. Make a note of when the noise starts and what it sounds like (grinding, rattling, squealing). This information helps the engineer narrow down whether the motor, pump, or bearing is involved.
Machine requires multiple button presses or does not start reliably. Record how many presses are needed and whether the issue is consistent. This may point to a door-latch or control-board fault occurring alongside the leak.
Check for standing water inside the drum or filter housing. If safe to do so, open the door and note whether water remains in the drum or drains slowly. Do not attempt to disassemble any part of the machine; simply observe and report to the engineer.

Frequently asked questions

Is it safe to keep using the washing machine while it's leaking?

No. Continued use risks water reaching electrical components, creating a shock hazard. Switch off and unplug the machine, then contact an engineer.

Could it just be a loose hose connection?

Loose inlet hoses typically leak at the connection point behind the machine. If water is pooling underneath during the cycle, the leak is likely internal—from the seal, heater, or pump—and requires professional diagnosis.

How much does a typical repair cost?

SMC Services charges for engineer attendance and parts. The final cost depends on which component has failed and labour time. Request a quotation when you book.

Why does the machine need two button presses to start?

This may indicate a fault in the door-latch mechanism or control board, sometimes linked to the same underlying issue causing the leak. The engineer will investigate during the repair.

Can the door seal be replaced at home?

Removing and refitting the door seal requires dismantling the outer casing and aligning components precisely. It is not a practical DIY task and should be left to a qualified engineer to ensure proper watertight reassembly.
