Miele G7856 dw with "F26" error code

Is there anything I can do as a homeowner? Service won't be available to call till Monday morning and the machine is just giving an F26 code, no water left in it, it got through a cycle to the point of cleaning (soap used up, dishes cleaned). No water on floor under it, seems okay

    I power off (turn off breaker), remove filters, open up to see the drain pump, move it by hand, reassemble, power on, run drain cycle. No more "F26" error on the G7856 Miele Dishwasher, it ran a rinse cycle right afterward with no problems.

  • geek0 Jan 09, 2009

    Actual solution: turned out to be over-sudsing. The "Somat" dishwasher cleaner we had run through apparently was overkill (despite being suggested in the manual). The repair guy said we should run at most 1/2 tab of the Miele detergent at a time, and NEVER use the dishwasher cleaners.

    Any time suds build up, he suggests white vinegar or baking soda in an empty load.

SOURCE: Bosch SHX46A dishwasher

I have a Bosch SHX46B05UC/14 and it stopped functioning right. It filled, it ran, it drained, it sounded okay, but I finally determined there wasn't enough circulation pump pressure to swing the spray arms. Turns out the problem was a pump pressure adjustment screw, accessible under the kick plate, had backed off--now if I can only figure out how to set it properly, low enough to clean the glassware, high enough not to break the pots and pans--or is it the other way around. I also found some beans in the drain sump (easy to remove cover plate from inside with a torx driver, large object trap not locked down properly and a riser for the upper spray arms not press fit sufficiently into pump outlet (I wonder if I blew the line while setting pump pressure. I AM looking for guidance on how to properly set the pump pressure, for the moment, I simply turned it into its spring loaded range and cranked it down a few turns.

SOURCE: Dishes are not clean; lots of soap residue

Try the combo liguidgel powder packets and wash on the potscrubber plus setting. We saw a drastic improvement with this setting. I have just about gotten out of the habit of thorough pre-washing, but I do rinse heavily soiled items.

SOURCE: dishwasher Soap scum left on dishes

the problem is hard water. There is a new product out called The Dishwasher Filtration System. It filters the water going into your dishwasher leaving your dishes spot free with every load. It is very affordable and fits right under the sink. You will be amazed how sparkling your dishes look just after one load. You will love this product. Get it at

I have a Miele g7856 and I just replaced the drain hose now I get a F2E code ?

The F 2E code indicates insufficient water coming into the dishwasher. Thus you should check that the shut-off valves for the incoming water lines are open. Make sure that the incoming water pressure hasn't decreased and that the water lines aren't kinked or blocked. You should also check the water inlet filters (at the screw connection of the hose) and the flow restrictor insert in the waterproof system.

Since the dishwasher was working before the drain hose was replaced, closed shut-off valves and kinked hoses are particularly likely. You may also want to replace the inlet hoses themselves. (Some anti-burst hoses will restrict the water flow if they detect a leak.)

I hope this helps.

Why am I getting an error code iCO on my frigidaire gallery dishwasher?

I just addressed a iCO error code on my 2 week old Frigidaire Gallery DW. I reset the circuit breaker as recommended online and it worked fine for another few days and then came back. Customer service cannot tell me what the error code means. They WILL NOT replace the DW, rather want to schedule a service appointment. I have no desire to repair a new DW so I am receiving a refund from the retailer I purchased from. On to the next brand!

Drain pump goes ON when ON-OFF button is pressed, even if the know selector is in OFF position and the machine is dry. There is no fault codes and the dishwasher complete the washing cycle OK, but when...

Seems that the drain pump circuit in the main program controller unit power and keeps on as there is no logic feedback to cut off the power. It can be that the drain is clogged and so the water level detect keeps sensing due to a fault. check the sensors , check the drain filters , check the machine LEVEL so that the water drains clearly to the drain pump.

F13 error code on Miele dishwasher. I can't find

The water valve on Miele dishwashers is built into the end of the water line where it hooks into your plumbing(in that box-looking assembly) Your best bet is to call Miele USA, I have had very good luck with their customer support system, they can usually diagnose your problem right over the phone.
