Why is my dishwasher making strange sounds? and putting rust spots on my dishes?
Tuesday, August 16th, 2011Question by sunnybunne: Why is my dishwasher making strange sounds? and putting rust spots on my dishes?
This is the order I noticed it, but the annoyance order is reversed.
Also the soap dispenser doesn’t dispense. The majority of powder is left all cakey dry in the morning. I phoned Electrolux (the company) and they said to clean out the cloged holes in the spinning things. I did that and it’s the same?
When I’m unloading theres rust spots all over the crockery some times cutlery too.
Its pretty ugly on our white and cream sets.
I phoned Electrolux and they said to clean the inside with stainless steel cleaner. But theres no visible rust on the inside so I don’t see the point?
She also said they’ve never heard of it before. And maybe the dishwashing powder is too acidic? We just use home brand and its worked fine in the fisher and Paykel we had in the previous house.
During the rinse cycle, its like horror movie screaming, far in the distance. its disturbing our sleep.
Haven’t phoned them about this one yet!
I recently switched to using vinegar in place of the rinse aid. But I don’t think that’s got anything to do with it. The problems were before that.
Any ideas, remedies?
Wow what, did you invent dishwashers Mike!
Thanks
Was thinking maybe as a possibility. the blue rubber thingy round the cup could be leaking. And the detergent gets all gooped up before it even gets released?
I’ve still got unexplained horror screams in the kitchen at night. Anymore ideas fixes??
Ohh I bet it’s the glasses screaming at the sight off my dinner plates with rust spots all over them.
Ok the sound of my dishwasher could be likened to those fireworks that they let off, and are know for they’re loud whining noises.

If the detergent cup doesn’t open, check the detergent cup, the bi-metal switch or wax motor, and the timer. Make sure that no dishes are blocking it from opening.
The cup that holds the detergents can get caked and gooped up with old detergent. You should try to clean away any old detergent. If you can’t clean the detergent away, you should replace the cup.
The bi-metal switch is activated by the timer and is an electrically operated device that bends when electricity is applied to it. It uses two different metals that are bonded together. As they warm up, they expand at different rates causing the metal to bend. The degree of bending can be set with a high degree of precision. Many devices use the bi-metal switch. A lot of newer dishwashers use a wax motor instead of the bi-metal switch. The wax motor has a wax block that gets heated up when the timer sends electricity to it. The wax expands as it gets heated up, and it pushes a plunger that opens the detergent door. Depending on how your dishwasher is wired, the switch may be wired through the motor circuitry or through the heating element. If the heating element is broken, there will be no electricity to properly activate the switch or heat the wax block in the wax motor to open the cup. If the motor doesn’t let enough electricity through its circuit, the bi-metal switch won’t operate properly, or the wax motor wax block won’t get heated up to expand and push the plunger.
On many dishwashers, an actuator arm links the timer to the detergent cup. When the timer reaches the correct time of the cycle, it activates a lever that opens the cup. If this link is broken or in any other respect faulty, the cup will stay closed, and won’t let the detergent into the dishwasher. Check this linkage and either fix or replace it.
