Omega Dishwasher Arms Not Spinning

Hi

I have an Omega dishwasher and lately it hasn’t been cleaning utensils well.

I checked all the pipes and drainage stuff but didn’t solve. Got a guy to inspect and he did exactly the same things which I had already done go online help. However he noticed that both upper and lower arms weren’t moving. He suggested we replace them both.

My concern is that what if the pump is not working properly and the not able to generate enough for the arms to move. I removed the arms and tried using garden hose and one of them did spin perfectly. This guy seemed to think the pump is OK. Everything else like draining and water jet through the arms is ok.

Don’t want to do hit and trial and replace the arms for 100 bucks and then find pump faulty.

Any advice?

    How old is it ? Buy a new one ?

    Omega are the cheap shit brand that massive developers use when they give you the $1 inclusions package. Everything in my house that was an "inclusion" was Omega, and every single one of those appliances has failed.

    If it is $100 to replace the parts, I assume that is excluding labour and you think it might be a pump, do what @boom says above and just replace the whole washer if it old enough.

    My understanding is that these work the same way as sprinklers, so I would go with that rather than what the guy has said! Put a GoPro in there and see if it is moving or not :)

    My family had two dishwashers growing up, my brother and I.

      Any issues with arms or pumps?

    Choice gave Omega dishwashers very poor ratings and did not recommend them.

    Replacement time?

      Not my choice too, but got the house with omega dishwasher!!
      Don’t have money to buy a good one I don’t want to buy another cheap omega

    I’d get the arms and take them outside and put the hose full blast down the core and see what happens, also check the plastic screw/nut that fixes the arm to the machine, I’ve had an issue before when the arms were clean of debris but central nut had potato peel in it, stopping the water before it even got to the arms. Not really worth spending more money on it. By a Bosch and move on.

    I had an Omega Bench Top dishwasher and now own a different brand. I had the same issue, and it turns out the holes on the end of the arms are small enough to be blocked by a grain of rice sized waste. This stopped mine from turning. They are easy to remove, and I just poke the foreign item out and shake until it falls out or try forcing water back through the other way. I'm not sure how it would work with a full sized dishwasher.

    To clarify: The hole on the end of the arm is what makes the arm on my bench top machines turn, so it was there where the blockage was.

      Most people don't realize dishes are to be rinsed before going into dishwasher to avoid blockage. Which kind of defeats the point. Dishwashers are useful for big loads but might be a false economy depending on the situation.

        It's pretty easy to miss something the size of a grain of rice in everyday usage even if you rinse which I admit I often don't if the items to be cleaned don't have anythin of substance on them.

        •  

          Yeah that’s correct and the same grain is somehow stuck somewhere causing issues

            @Ehty: The only other issues I have ever had with arms not spinning is that the diameter of some dishes cause them to protrude down through the rack further and actually block the arm from spinning or cutlery that is too long. Both of these issues were very hard to diagnose as it was mere mm in it. Sounds like you actually have a mechanical problem though. Hope you manage to sort it out.

        Bullcrap, I've been putting dishes and pots to the dishwasher and never rinsed a single one and they always come out spotless, except when there was some thing protruding below the rack and block the rotating arm. The most I'd do were scrapping the leftover as manual recommend.
        Funny things was I had that mindset like yours before spending money on them but have since never looked back.

        Don’t rinse. Scrape. Rinsing wastes bucketloads of water. Your dishwasher will wash more effectively with some extra greases from food in there.

    Do they spin freely by hand when in the machine?

    It’s either not enough pressure to spin them, there is something blocking the jets or there is something causing friction in the spin.

    Sounds like you’ve tested for blockages. Check pressure by sticking in a waterproof camera during cycle or opening the door mid cycle and looking at where the water is spraying.

    •  

      I have narrowed it down to low pump pressure but the water spraying is good through the arm holes.
      Just they don’t spin!
      I don’t have a camera but I open the door mid cycle couple of times only to find the arms in same position, not moved.

        ask your friend to borrow your go pro, I saw few youtube people putting a go pro into the dishwasher.

    I need to take out the dishwasher but this inlet tap is not opening?
    how do I open this thing?

      That’s a leak stop valve. Some sort of electrickery that shuts off the water is the machine thinks there is a leak.

    The arms may be blocked with food, seeds, plastic etc

    Two options are to try and clean them out or replace them.

    Generally low pump pressure when give off odd sounds or a hum which may be it seizing up or a faulty capacitor.
