WHAT IS THE PRICE OF HANNING ELECTRO WERKE DRAIN PUMP DP025-274 A01

sounds like the pump is locked up and needs replaced. try the internet appliance parts

Cod deblocare blaupunkt-werke gmbh seria bp 4495s2621334 please !!

Put a 120v load on it.

error 6 relates to a blocked drain pump. if the drain pump is working ok check if the tank level sensor is operating or if the air chamber in the wash tank is blocked.
error 21 relates to the drain pump being activated. normally related to error 6.
also check water inlet solenoid valve is working correctly. ie not blocked or passing.
all parts of the machine can be activated manually by entering service mode.
when machine is off press service button or switch on main pcb.
p00 appears. press and hold main wash button. --- appears. using the long and short wash buttons you can scroll through parts of the machine. displayed as a01 a02 a03 etc.drain pump is a12 solenoid valve is a13. these are activated by pressing the button. when activating the drain pump the display will count down. this number is the water level in the wash tank. if it's counting down the level sensor is ok.
hope this helps

the A01 fault code is nearly always down to the pcb, 99% of the time in fact, its a common fault, but not common enough for ariston to be responsible for boilers out of the warantee. you can normaly check this yourself, while the tap is running check if the electrodes are still sparking even after the gas had lit, this means the pcb is not detecting the flame and trying to relight. eventualy it will lock out with a A01 code, if u reset it might work for a short time but eventualy u will get to the stage where it will no longer resart.

if your handy you can replace the pcb yourself, there is someone selling them on ebay for £85 thats a steel, its half the trade price never mind retail

A01 means The micro-switch in the base tray has been closed for 9 seconds to signal the alarm.
Water is leaking from components or hoses in the base of the machine.
Programme will abort and the drain pump will be energised.

its not definately the pcb. change the detection sensor first( £3.20p). if this doesnt fix a01 fault then change the main pcb(£145).

A01 keeps coming up. Can you help

Error message A01 means -Acqua stop operated due to a leak or overfill. Check if there is still water in the machine after it stop pumping. In case you still have water - your problem is with the pump or with a blockage drain line. If there is no water in the machin, it might be a water level sensor issue - stuck physically in the high level position or become defective. Try to reduced the water presure and leveled it up by the water entrance tap to the machine, it might solve your problem. Goog luck !!
