Dismantle Emerson insink erator

Under the counter there is a weight on the hose. If it gets stuck on something you placed in the cabinet under the counter then the weight can't help you put the faucet head back in the fixture. Check the cabinet under so that the hose and weight are free.

Must replace tank.
Insinkerator stainless steel tank does not have anode rod to protect against depleted tank wall.

Check all the connections, take the cover off after you shut down the power. If the connectors are not leaking, replace it

1) Copy following link for troubleshoot and parts resources, and manuals with warranty information:

2) New unit would be best solution. And possibly cheapest solution. Otherwise you might be installing and un-installing more than once or twice ... which is fun if you have time, and other housemates don't mind kitchen project tools, water and mess.

3) If you can disassemble the disposal, you might be able to make your own gasket using kits and sealant from local auto parts .... assuming the metal was not mis-cast during manufacture and is warped so it never seals.

Yah --- if it is humming - usually means it is jammed -- check it out on the sides of the blades. If it is over 2years with heavy usage - get a new one

Usually happens when the temperature is set too high, check your instruction book and set it to the advised temp. Also the filter in the nozzle may need a clean.

The first thing I would check would be the switch. then the thermostat then the element.I would also check for any burnt insulation which could allow a short to ground.
My gut feeling would be the element but I like to eliminate the less expensive items first. Hope this helps. Thank you and have a good holidays.

the valve in the tank is bad,, this I beleive is the vent hose the blue one and should only have air in it, to keep it from making noises when in use,, take it off make sure it is clear,, how old is the unit,, it might be itme to chang it, insink erator has there own service people that they wil send call the 1800 number on the front of it the will help you futher
