Dishwasher motor Humming

The Eastern Cape has become one of the most preferred holiday destination in South Africa. Which means that more people are buying holiday homes with appliances that is standing in dormant for the most year. This slumbering periods has all sorts of negative-effects on domestic appliances

Household appliances are social bodies and they just love been around people. They also at their happiest when you use them - they are meant to be open and closed all day long. 

All they ask in return is a little Tender loving care (TLC). A hot soapy rub will do wonders for their outer and in return they will shine for you.

What about the inner-side of Domestic Appliance?

Most appliances just can't handle the loneliness of been left alone at home for weeks, without someone to use or talk to them. 
Appliances handle these isolation period difficultly. Some fall to pieces and rust away. Other just cracked and start leaking.

Worse some just seize-up. The electric-pump-motors seize up because a little bit of soap residue that was left behind (unknowingly) in the pump
Soap and water are the best supplements you can give your Dishwasher and Washing machine but like most supplements if not taken at the right time it can mess things up.

After the dishwasher/washing machine has drained its water on the last cycle, it always leaves behind some little soapy-water in the hoses. Once the water has evaporated over a period of time - the soap chemical now acts as glue, gluing together the seals onto pulsator shaft. When you want to use the appliance again after many weeks it only humm's.
  • Humming after - The machine takes in water but once it should go over to was cycle nothing happens. The faint humming noise is telling you that the motor is stuck (glued) and cannot turn. Whatever you do do not switch it on again because you could cause the motor to overheat and burnout. 
  •  Humming before - taking in water means it is the drain pump that has gone on the blink. In most cleaing appliances the drain pump is the first part that comes in operation once the machine is switch on.
In both cases call your local professional appliance repairer too service the appliance before any real damage is done.

This now raises another question, "How do one prevent this scenario from occurring"

Unfortunately I do not really have an answer how you can prevent this "glue-ing" from happening but over the years of repairing appliances I have come across many people that does different things to their appliance to prevent storage-damage.

  • Vinegar- pour half a cup of white vinegar in the dishwasher or washing machine after it has done its final rinse
  • Bleach - the hypochlorite in the bleach also acts as a neutralizer for the soap
  • Draining - Putting the drain hose flat on the ground, letting all the water run out
Do you have a better method of preventing 'glueing". Please send us your suggestions

In the meantime enjoy your coastal holiday
