Hello, Welcome to FixYa. Based on your description it sounds like the emergency overfill switch has been actuated. Here`s what to do and what to look for. ( unbeknownst to many this is built by B/S/H/...or better known in north america as BOSCH ) **Turn off the breaker/power at your homes service panel...safety first of course** Remove the the bottom panel, referred to as a toe panel or kickplate, essentially the lower service panel. When you remove the outer toe panel, (typically black in color, though sometimes white depending on the model, customization etc.) there will be another small "L" shaped panel which is non finished steel, I find removing that allows much easier access as well. This panel can be somewhat more difficult as it secures the plastic channeling for the wires but if you observe closely you`ll see it does "snap" out of place...carefully. Once the panel has been removed check for any obvious signs of water in the base ( the unit has a plastic overfill basin with a float which will actuate an emergency overfill cycle, hence the drain pump runs & runs ) If you don`t witness any water in this area, direct your attention to the left in this basin/bottom ( from the front to be sure ) and you should see a device which will resemble a "stir stick" you`d use for coffee etc. it will be a red in color stick. With the aid of a wooden spoon, long screwdriver, or if you can manage to reach by hand, lift it up and down gently and listen for a "click". If there is no sign of water and you can here the "click" when lifting up and down the float actuater ( red stick ) then turn the machine back on and give it a try before reassembling the toe panel so you can observe for any possible leaks. Let me know what you find. This is the most likely cause of the symptom you are describing so we can move forward if this doesn`t resolve the issue. Thanks for choosing FixYa. Good luck. macmarkus :)

    This is an example of what to look for regarding the overfill actuator ( red stick ) I referred to...








    and of course the float, ( round foam disc with gray link ) make sure there is no water present around it or you won`t be able to reset the overfill actuator ( red stick ) ...






    Again, let me know how you make out.

    The float chamber to the left of the stick stuck, keeping the pump in an actuated position. A little hot water into the chamber released the greese causing the float to stick.
    Recommend once a month flushing the dishwaser through with LIMESCALE and GREESE remover. Have fun.

ENGEL STILL GETS COLD BUT RUNS VERY HOT AND USES MORE POWER


FRIDGE COILS SEEM VERY HOT:

The condenser coils do get hot. They can even be to hot to comfortably touch and this is normal.

The refrigerator should not run constantly.

Running constantly and never cycling off can indicate a cooling problem.

One thing to try is to wait till it has been running a few minutes then open the door and turn your cycling thermostat towards the off position. It should cycle off before getting to the off position on the dial.

If it does not cycle off then it's not getting cold enough to satisfy the thermostat. This is likely the reason the refrigerator runs all the time.

A thermometer in a glass of water can be used to check the temperatures in the refrigerator section.

You can check that all fans are running.

The eco light is flashing constantly on my Dishlex Global 300 dishwasher, it is making a noise like a pump is running continously, but the unit will not operate. Can you give me some possible faults and...


Hi,

The symptoms on a Dishlex Global 300 dishwasher:
  • eco light is flashing constantly;
  • noise on pump running continuously;
  • but the unit will not operate.
Possible corrective actions include:
  • water level - pls check incoming water pressure, filter, water level sensor, water valve;
  • base/bottom overflow sensor - there is a float switch in the base of the machine inside a small plastic dish. Behind the kick panel, access through a metal lid/panel/cover secured by 2 small screws. Dry completely the area;
  • Air/dry/ventilate the unit/system for a couple of days;
  • reduce incoming water pressure.
Hope that this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Water pump runs constantly


First we have to figure out where the water is going, because if the pump is running the water has to go somewhere. either the boiler or coming out the groupheads or there is a leak? If the groupheads check the manual switches make sure they are in the off position. If the boiler check the wire on the level probe, the inlet solenoid and sight glass to see the amount of water in the boiler. If there are no leaks then there might be a problem with the mainboard.

Do you still have water down the bottom of the unit? Usually when you are hearing that pump noise that is from the drain pump and the reason it is constantly running is usually because there is an obstruction either blocking the hose or blocking the pump from evacuating all the water from the unit. This is a fairly common issue on all dishwashers. Remove the spinner on the inside of your unit and assure that there is nothing blocking the port exit hole. If there is not then you will have to de-install the dishwasher and pull the unit out and remove the drain hose to assure nothing is stuck inside the hose and at its connection point usually to the disposal under your sink. Remember to turn off the water as well as the power before you de-install. If you have any further questions message me back. I await your reply
Thank you,
Rick

Drain pump won't turn off


Hi,

The reason the drain pump continously runs is because it is trying to remove any water too avoid any further flood as there is a flood in the base of the unit which activates the float switch and constantly activates the drain pump until the water has gone. Isolate the unit at the power switch and remove the bottom panel under the door panel. Dry up the water as best possible with a towel. Run the unit again and check for any water leaks. You may just have over sudded the unit with too much detergent. Only use 2 teaspoons of powder. To start with while testing don't use any detergent. Good luck

Hope this helps.

My saniflow is running constantly.


Shut the water off to see if it stops running. if so the flush valve seat has calcium build up and needs to be cleaned start by using CLR to help dissolve the calcium. If running water is not the problem, the mercerator is jammed with paper and will need to be cleared.
