What is the purpose of an overload?
Overload relays cut off current to the motor when a high-current situation develops due to a ground fault, short circuit, phase failure, or mechanical jamming. They are an inexpensive way of avoiding downtime for repair or replacement of failed motors from excessive current. Too much current flowing through these wires causes an overloaded circuit. And there are a few possible reasons why: Too many appliances (via extension sockets or leads) are plugged into one circuit. A new microwave is plugged into a cooker hood socket.Unlike a short circuit (a fault between conductors that causes a sudden, intense current flow), an overload happens when too many high-power devices are connected at the same time. This phenomenon can occur in both residential and industrial installations and is dangerous because it can damage equipment or start fires.
What is the common problem of a coffee machine?
Clogging is another common culprit behind noisy coffee machines. Residues and mineral deposits can accumulate in the water or coffee grounds. Regular descaling will alleviate this problem. If you live in an area with hard water, using bottled water can also help. If your coffee machine is powering on but not brewing, the culprit might be a blocked water line or heating element. Mineral buildup from hard water can clog these components, preventing the water from reaching the right temperature or flowing into the brew basket[^2^].A damaged button or a blown fuse could be the culprit in your coffee maker not turning on.The water filter is blocked You can try descaling your appliance to see if solves the problem; and if that doesn’t work, you can also try dismantling the coffee machine to see if it’s possible to take the filter out and give it a more thorough clean.When your coffee maker stops pumping water, the appliance probably needs to be descaled. Hard water build-up may be affecting your coffee machine’s ability to pump water through it to make coffee. Simply run a descaling cycle to clear the build-up.
