Dualit coffee machine leaking water underneath
My Dualit coffee machine (Cafe Cino), nearly 2 years old — there is a puddle of water under the machine after every use. Is this something I can fix myself or do I need an engineer?

A puddle underneath after every use usually means a leak on the water side rather than a brewing issue, but there are a few simple things you can check first before deciding on a repair.
1. Check it isn’t just overflow or spill water Empty and refit the drip tray and water tank, then dry the base and worktop completely. Run the machine again and see whether the water is coming from the tray area or genuinely from underneath the machine.
2. Inspect the water tank and valve Remove the tank and check for hairline cracks. Also look at the small valve/seal where the tank sits onto the machine. If that seal is damaged or not seating properly, water can slowly leak into the base.
3. Check for leaks during filling or steaming Watch carefully while it is heating, brewing, or frothing. If the leak only appears when the pump is running, it could be a split internal hose, loose clip, or a leaking connection.
4. Look for scale-related leaks Heavy limescale can cause valves not to seal properly. If descaling is overdue, carry out the manufacturer’s descaling routine first and see if it improves.
5. If water is clearly coming from inside the machine Isolate it from the mains before removing any covers or inspecting internal parts. Internal leaks often involve hoses, pump connections, seals, or the boiler/thermoblock area. These are usually repairable, but access can be awkward.
If it’s under 2 years old, also check whether it is still under warranty, as opening it may affect that. For any internal mains-related work, it’s best to use a qualified engineer.

Safety first — read before actioning advice
Never work on a live appliance
Always unplug it at the mains before going near it with any tools.
Never attempt gas work
By law, gas appliances must only be worked on by a Gas Safe registered engineer. If your fault involves gas, stop and call a professional — do not attempt it yourself.
Watch for sharp edges
Outer panels are smooth, but internal parts are full of sharp machined edges. Wear protective gloves and arm sleeves.
Water appliances can leak
Turn off the water supply before disconnecting any hoses.
Know your limits
If you're not confident testing or working inside the appliance, STOP and call a professional.
