Freezer icing up or frosting excessively (Beko & Hotpoint)

✅ Safe to check yourself

This is a common, low-risk check most people can do safely. Always unplug the appliance (or isolate power) before touching internal parts.

Quick TipTake a photo of the appliance's model/serial number sticker now — you'll want it if this does end up needing a part or an engineer.

A build-up of ice on the back or sides of a freezer compartment (as opposed to normal light frost) almost always means warm, moist air is getting in more than it should — usually the door seal, or the door being left open too often or too long.

What to check first

  1. Check the door seal for gaps, tears, or a build-up of ice/debris preventing a full seal — the paper test described in our “not cooling” guide works here too.
  2. Check the door is closing fully every time — a door that looks shut but isn’t quite latched is a common, easily missed cause.
  3. Avoid leaving the door open for extended periods while loading/unloading, and try not to put warm food directly into the freezer.
  4. If your freezer isn’t a frost-free/no-frost model, some ice build-up over time is normal and expected — these models need periodic manual defrosting (check your manual for how often), and excessive ice is often simply a sign it’s overdue.

When to call an engineer

If the door seal is intact, the door closes properly, and it’s a frost-free model that’s icing up anyway, the automatic defrost heater or its timer/sensor has likely failed — this needs a professional diagnosis, as it involves internal electrical components.
