Question about Dishwashers

2 Answers

Hoover Heds668-80 dishwasher, first fault was a broken door lock which has been replaced. The machine has done one pre-rinse and one full wash cycle. Now whenever we try to run any program it starts, drains, pauses then after 5 minutes beeps 30 times with the pre-rinse and wash lights on.

    if i set the machine to run just the pre-rinse cycle (program 6) the machine takes in water and the cycle progresses normally or seems to progress normally. The inside of the machine is wet. It only seems to be the washing cycles that cause the beeping.

    Many thanks for your help! When turning the machine upside down and removing the bottom plate we found the anti flood float stuck at its highest level actuating a switch and a broken wire on anothe sensor.

Hi.

The two lights and the beeping will normally indicate long filling rather than drain problem. For this reason the fault is detected at start.

As first thing follow the troubleshooting indicated on the user manual. Check the drain well, and remove eventual water and debris from the bottom of the tub and from the drain well and filter.

After that reset the machine by holding down the start button for about 8 seconds.
If that does not work also try resetting the machine by disconnecting power. Trip the circuit breaker or try disconnecting the power cord for two minutes to reset the appliance.

If still no luck, then there is a fault.

If the problem is long filling, in that case check if there is water getting in the machine.
If there is no water at all, the first part to be tested is the inlet valve.
The valve is tested reading Ohms at its contacts with the multimeter set at Rx1. When the valve solenoid is broken, the reading will return no continuity.

If water is getting into the machine, then part to be tested is the water level sensor. On Hoover branded machines this is usually a float sensor. The sensor must be checked to ensure the floater is not stuck and that the switch is opening and closing the circuit.

If your machine is faulty and the error does not clear by holding down the start button, as first thing call the Hoover at the number listed on the owners manual. They will give you part prices and a quote on repair.

Regards.

OK above is a service and repair manual, although, a generic one, they are all essentially the same, and this can be used to troubleshoot and diagnose the problem, and thus repair it.
This Fix below, may NOT apply, however, it is amazing just how many times, regardless of the "Cause" that the doing of the "Procedure" actually fixes the unit for good. So is worth a try.... Ok so your dishwasher won't do anything... it justs sits there and "Hums" you can't make it respond to any controls, and the ONLY way to Stop it. is to unplug the unit, replugging back in it simply "Hums" again and will do nothing.
Now this happens because, the STOP Button, is pressed and the "Door Opened", during the Wash Cycle. This should NOT be done. You shouldNEVER TURN IT OFF MID-CYCLE. you should instead, Simply, pull on the handle, to Open the door, the system will take care of everything, after, you close it,and pick up where it left off. The turning OFF, makes the machine "Think" that a New Cycle, is going to be done, before the old one is finished, and resets itself to do it all again. But it still has water, that's not meant to be there so it must dump it out.
Now, the FIX. Take the Dishwasher, out, and tip over on it's side, tip to about a 45' angle. Water will come out from underneath, this is from a small "Overflow" reservoir. this reservoir has an "Anti-Flood" switch. The removing of this water will "Reset" this Switch, and allow the dishwasher to work again.
So what happens, is this, when the STOP button is pressed Mid-Cycle, the machine must "Dump" whatever water is still in the machine, into the "Overflow Reservoir". This water then causes the Anti-flood switch to jam, and this stops the machine, until it is reset,by the above method.

Why doesn't it go past the "pre-rinse" stage?


I would say that there's a very high probability that the heater in the machine has failed. It does the cold pre-rinse but when it gos to the next stage and tries to engage the water heater it detects an open circuit and faults out. You will find replacement heaters on eBay and probably videos on how to replace on YouTube

'low rinse' stuck on with full rinse aid, can't start wash cycle


Actually, if you look closely at that Low Rinse button or emblem, you will see a little lock symbol above the words "Low Rinse", and I'll bet THAT light is the one that is on. Basically, you have the control lock (or child-lock) turned on. To turn it off, you have to press and hold the Sanitize button for 3 to 5 seconds until that light goes off. Now your dishwasher will work!

The manufacturer has assigned this error or fault code to indicate a problem with the water circulation pump motor. Turn the appliance off for 30 minutes to allow it to cool. Then, restart the cycle. If the error code returns check the wiring to the pump motor. Also, if the wash impeller is broken this error can appear. If the impeller and wire harness check out, and the code keeps returning, you will probably need to replace the pump and motor assembly.

Hoover Nextra HNF2127 washing machine. Lights flashing at finish


Hi


Thanks for using FixYa. The start and pre-wash usually flash due to a clogged drain hose or the water pump. You’ll need to drain the water out of the base and also check to see if there's something stuck inside the pump or the drain hose connected to the pump (pump is usually located at the bottom and towards the back of the washing machine). If the drain line isn't clogged, you may have a problem with the water pump such as a frozen pulley or a broken impeller. If that's the case replace the water pump. Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

My hoover washing machine won't spray rinse or deep rinse on cold


Rinse cycles are normally with cold water only.

I believe you have a faulty cold water inlet valve. To confirm, put the machine on a cold only wash cycle, and see if it fill up with water.

If it does, then the valve is O.K. In that case the problem you are having with the rinse cycle is most likely a timmer fault.

Good Luck

My 5 year old Hoover 500 mb has started to stop mid cycle or not progress through the cycle !


Mate, I just had the same fault with the same model machine. The local machine repair man called me (i'm a sparky) to double check things for him. The macine stopped at the pre wash rinse part of the cycle every load. He replaced the timer with two NEW ones which both had the same fault as the original. We now suspect an inherrent fault in the timer design but as yet dont have an answer.
