You've just pressed start on the washing machine and the living room lights dim or flicker for a second. It's frustrating - and a bit disconcerting. Is your house about to catch fire? Relax. It's usually a sign of something straightforward, but it's worth understanding what's going on.
The Why: What's Actually Going On
When your washing machine kicks in, its motor draws a sudden surge of current (called inrush current). If your lights are on the same circuit - or share a cable back to the consumer unit - that demand causes a temporary voltage drop. Think of it like several taps sharing one pipe: when one opens fully, the others get less flow for a moment. In older properties across Margate and Ramsgate, circuits were often designed for lighter loads. Modern washing machines, especially with heated washes, can pull 2-3 kW. If the circuit is already near capacity, or the wiring is old and has higher resistance, that voltage dip shows up as flickering lights.
Roy's Pro Tip
Try running the washing machine on a cooler wash or at a different time of day when fewer appliances are on. If the flickering reduces, it's likely voltage drop. If it's severe or constant, your circuit may need upgrading.
Safety Warning
Call an electrician if: the flickering is severe or prolonged; you hear crackling or buzzing; the consumer unit trips when you use the washing machine; or the lights flicker even when the machine isn't running.
