Garbage disposal humming, jammed or leaking in Hamilton? Learn what each symptom means, what you can safely try, and when to call for repair.
A garbage disposal usually tells you what is wrong by the sound it makes, or the mess it leaves under the sink. The trick is knowing which problems you can safely sort out yourself, and which need a technician. Before anything else, one rule matters most.
Safety first: never put your hand into the disposal, even when it is switched off. Always cut the power at the wall switch, and unplug the unit or turn off its breaker before checking anything inside.
This is the classic jam. The motor is getting power but something is blocking the grinding plate. Left running, a humming disposal can burn out the motor, so switch it off quickly. With the power off, you can usually free it yourself:
1. Turn off the disposal and the wall switch.
2. Use the hex (Allen) key in the slot on the underside of the unit to turn the flywheel back and forth and free the jam.
3. Press the red reset button on the bottom of the unit.
4. Restore power and test. If it still hums, stop and call a technician.
No sound usually points to power rather than a jam. Check that it is plugged in, press the reset button on the underside, and check your breaker. If there is still nothing, the switch, wiring or motor may have failed, which is a job for a professional.
Water pooling in the cabinet is worth acting on quickly, since it can damage the cabinet base. Leaks commonly come from the sink flange at the top, the hose connections, or a cracked body on an older unit. A cracked body normally means the disposal needs replacing, and we can confirm which it is.
If the sink backs up, avoid chemical drain cleaners, which can damage the unit and its seals. Slow draining is often a clog in the disposal or the trap below it. A technician can clear it and check that nothing has damaged the grinding components.
A sudden rattle is often a foreign object, such as cutlery or a bone fragment. With the power off, look inside with a flashlight and remove anything you can see using tongs, never your fingers. If the noise continues once it is clear, the grinding plate or a bearing may be worn.
Persistent jams, humming that will not clear, leaks, a unit that will not power on, or ongoing noise all point to a repair, such as a worn motor, a seized flywheel or a failed seal.
