Question about Bosch Nexxt Premium WFMC6400UC Front Load Washer

1 Answer

I get a check water tap error 2 to 4 times a load

On my Bosch WFMC6400 i get a "check water tap" message multiple times per load, hot or cold. I push the start button and the washer starts. I cleaned out the hoses, the cold was clean and the hot had a little sediment in it. Should I replace the valves or look somewhere else?

I have this problem. This code is due to restriction of water flow. In my case, we have sand in our water, and I have installed a filter between the water line and the washer. When it gets clogged, the flow is restricted and the Check Water Tap message appears. Your washer has filters on the back of the washer itself that may be clogged and need cleaning (which is why I installed the water filter between the washer & water line to prevent it from getting into the washer filter). Your washer manual shows you how to check/clean them. Also, you may have low water pressure during summer months due to lawn watering in your area that could cause this lower water pressure.

24460 washer just installed but water will not come in when press start , 86630 dryer works fine .


Hi from retired Englishman in SW France,
(Although you say that the washer is 'just installed', you do not say whether it is new or not)

If you have checked that the hot and cold water taps are turned on fully and the hoses are not kinked or squashed at the back, it is worth while checking both the hot and cold water inlet filters. Turn the taps off and remove both hoses at the washer end. Inside each inlet port there is normally a little filter which should just slide out. Clean if necessary and replace each one and the hoses. If after turning the taps back on there is no improvement, the problem is symptomatic of a malfunctioning hot or cold water control valve.
If the washer is new contact the vendor!!! I assume it is still under some sort of guarantee/warantee? You can nulify any guarantee if you attempt to fix problem before contacting vendor.
If it is not new you will need a service call, sorry ;-0(

Is it waiting for water inlet perhaps?

It often flashes ea or af and doesnt want to light


Before calling service technician, open following links for troubleshoot resources including common error codes, Bosch contact information, link to service manuals, and possible product manual
http://waterheatertimer.org/Troubleshoot-Bosch-Tankless-water-heater.html
http://www.boschhotwater.com/HelpfulResources/TechnicalSupport/BoschAquaStarModels/2400ESTechSupport/Troubleshooting/tabid/1295/Default.aspx

Call Bosch 800-642-3111
Multiple error codes can mean PC board failure.
AF might be A9, but not sure.
EA is 'no flame ionization detected with water flow'
  1. Verify that all manual gas shut off valves are open.
  2. Check gas type.
  3. Reset error code and open a water tap to cycle the heater in an effort to purge air on new installations. Cycling hot water tap on and off multiple times may be necessary. If heater still faults with EA error code, have a licensed gas technician properly purge air out of the gas line leading to the water heater.
  4. Check three wire connections to ignition group on the lower front of the heat exchanger are secure.
  5. Check gas pressure.
  6. Check venting specifications are met. Improper venting may cause premature failure of the flame sensor rod.
  7. Check that the minimum power fan speed has been adjusted to the proper value.
  8. Observe inside the viewing window of the heat exchanger when a hot water tap is opened. Sparking should be followed by a steady blue flame. If flame is unstable or yellow with proper gas pressure.

Water takes 30 sec to cover 10m from heater to tap


body { background: #FFFFFF; margin: 0px; padding: 4px; font-family: arial, verdana, sans-serif; font-size: 10pt; } p { margin:0px; padding:0px; } .spwrap { background: transparent url(/wysiwyg_rte/misspell.gif) repeat-x scroll center bottom; } You are talking about length of time to get hot water from water heater.What diameter pipe are you talking about? What type of faucet do you have?
1/2" pipe has inside diameter of .54" and holds 1.2 gallons per 100 feet
10 meters is 32 feet and holds .4 gallons
Average faucet puts out 2 gallons per minute, so 30 seconds you should get 1 gallon of water.
Put a bucket under faucet and check amount of water flow.

Assuming you draw just hot water from the faucet, then 30 seconds is slow for receiving hot water.
If you have single-handle faucet and raise handle straight up in middle, then you are drawing half hot and half cold, so it would take 30 seconds for hot to arrive.

If hot water is slow, the problem might be crossover.
http://waterheatertimer.org/Crossover.html
or low water pressure due to clog in water line
http://waterheatertimer.org/Low-hot-water-pressure.html
Other problems could include clogged water filter, clogged water softener, defective pressure valve, and low water pressure.

Above are the manuals required to diagnose and service your error code.

EA: No flame ionization detected with water flow.
Verify that all manual gas shut off valves are open. Check gas type. Reset error code and open a water tap to cycle the heater in an effort to purge air on new installations. Cycling hot water tap on and off multiple times may be necessary. If heater still faults with EA error code, have a licensed gas technician properly purge air out of the gas line leading to the water heater. Check three wire connections to ignition group on the lower front of the heat exchanger are secure. Check gas pressure. Check venting specifications are met. Improper venting may cause premature failure of the flame sensor rod. Check that the minimum power fan speed has been adjusted to the proper value. Observe inside the viewing window of the heat exchanger when a hot water tap is opened. Sparking should be followed by a steady blue flame. If flame is unstable or yellow with proper gas pressure.
