Zanussi dishwasher DA 6141 6 years old

F6 error fault code
This is the Water tap closed. What that means is that the flow meter is not recording water entering the dishwasher, this can be a water tap turned off (suprisingly more common than you'd think, after new flooring or decorating has taken place),
water hose kinked or blocked, the dishwasher water soleniod valve defective.

Try throttling back (reducing the water flow) the valve that feeds the machine. With the sink tap/faucet running the pressure into the dishwasher is reduced. Is the feed pipe kinked or blocked in some way as there might be a sensor in the machine that doesn't like it when water is "jetted" in under pressure. It would act like putting your thumb over the end of a hose when washing a car.

Check water coming into machine, check taps, check drain hose for kinks and make sure water drains well into undersink spigot.

The problem is hard water. There is a new product out called the dishwasher filtration system. It filters the water before it enters your dishwasher. It works amazing and has a money back guarantee. You will love the way your dishes look after the first load. It is also very affordable (like 70 bucks). Go to www.dishwasherfilter.com to find out more info.

Your dishwasher may pre-heat the water. If so, and if the water entering the dishwasher is cool, the heater may take up to half an hour to heat the water.

To avoid the wait, increase the incoming water temperature before turning on the dishwasher. Do that by running the kitchen sink faucet until the water runs hot. Or increase the temperature of the hot water to the entire house at the hot water heater.

If there's no water entering your dishwasher, check these:

Water-inlet valve
Float switch
Water-inlet valve
The water-inlet valve lets water enter the machine. If this valve is defective, you need to completely
replace it. It's usually located behind the lower access panel on the left or right side. It's the device
with the main water line (usually copper) from the house, a rubber tube to the dishwasher, and two
wires attached to it.

Float switch
The float switch is a small electrical switch that's located right below the dishwasher "floor."
Above the switch, on the inside of the dishwasher, is a plastic cylinder that floats up as water fills
the dishwasher. If this switch is defective, or if the plastic float gets caught or trapped in the raised
position, the water can't enter the dishwasher. If the float switch is defective, you need to replace it.

I have a similar problem.When the water stops entering,I momentarily turn on my main kitchen cold water tap, and believe it or not,the machine carries on working!!

Here is what happened, you pulled the door open without pressing cancel and allowing it to pump the water out, hence the "flooding in the bottom". This is just one reason why it maybe blinking, there is a water sensor in the bottom. If your dishwasher is hooked up properly to any decent garbage disposal, run the disposal for about 30 seconds to a minute. This should pump the water out, more like activate a light siphoning affect. It should work as normal. If you are not having luck with that, detach the DW drain get it low and let it siphon.

I got this with another dishwasher. On that one it meant the water wasn't feeding into it (tap switched off, kink in inlet tube, etc.)
