Question about Bosch Dishwashers

1 Answer

Started with E01 and E25

I have replaced the power board, drain pump and return valve. I have snaked all the drain lines in this model there are two one that goes from the drain hose to the back of the unit and then another one that attaches from the back of the unit to the air gap. I have taken off the air gap and checked for blockages and there are none. I checked the garbage disposal line and found no clogs. The code I am still left with is E01. This unit has very good pressure entering into the tub from the valve. Please does anyone have any ideas?

The E01 fault code means that the dishwasher has suffered a power module failure.
The programming of replacement power modules E01 up until E05 has been locked down by Bosch so in the event of an error code of this type it's recommended that you contact a Bosch approved dishwasher engineer.

Testimonial: "Thank you. It seems kind of retarded that I can't just put a power module in the dishwasher without having to contact a "Bosch" specialist. Especially , when I can purchase the part locally. I installed a new power module . So I am kind of disappointed. Thank you for your help"

Belt, Water Pump

Although few dishwashers have a water pump belt, if the dishwasher won't drain there might be a worn or broken water pump belt. After removing the lower kick panel the motor can be seen in the front, the water pump belt is on the bottom of the motor.

Pump and Motor Assembly

If the dishwasher won't drain, the pump and motor assembly might be defective. If the motor runs during the drain cycle, check for a blockage in the drain line. If the motor won't run during the drain cycle or if it just hums when it should be running, the pump and motor assembly might need to be replaced.

Clogged or Improperly Installed Garbage Disposer

If the dishwasher won't drain and the garbage disposer was installed recently, the installer might have forgotten to knock out the drain plug from this disposer. All garbage disposers are sold with a solid plug in the drain tube for situations where a dishwasher isn't connected. However, if the dishwasher is connected, the plug will need to be removed. If the disposer wasn't replaced recently, remove the dishwasher drain hose from the disposer and clean out both the fitting on the disposer and the end of the drain hose. These are the most common places to find an obstruction if the dishwasher won't drain.


Drain Hose

If the dishwasher won't drain the drain hose might be clogged. Remove the drain hose from both the dishwasher and the sink drain to clean it out. The most common place for an obstruction is at the garbage disposer.

Check Valve

If the dishwasher won't drain the check valve might be stuck closed. The check valve is a device which prevents water from returning to the dishwasher after it has drained. If the valve gets stuck closed, it will prevent the water from draining. The check valve is located in or at the outlet of the pump that the drain hose attaches to. Sometimes the check valve is accessed from the inside of the unit depending on the model.

Check Ball

If the dishwasher won't drain the check ball might be stuck. The check ball is a small plastic ball in the check valve which prevents water from returning to the dishwasher after it has drained. If the ball gets stuck, it will prevent the water from draining also. The check valve is the device that the drain hose is attached to on the dishwasher.

Tip

F02 and F09 - valid for Whirlpool Duet front load washer, HE3, HE3T Kenmore,...


Hi.

This tip is valid for valid for Whirlpool Duet front load washer, HE3, HE3T Kenmore,Fagor, amd more washers built by Whirlpool group.

F02 means that there is a drain problem, and F09 is overflow condition. When you get both error , it is usually because of a faulty pressure switch. Better testing the drain system as described below , before replacing the pressure switch..

To start try clearing the error by disconnecting the power cord or tripping the circuit breaker for five minutes. If you can clear the error, then the problem was just temporary.

The drain pump must be accessed as the drain hose is probably clogged. Also drain pump must be tested and eventually replaced.

If you get the error , but there is no water inside, and drain system is working correctly, then test and eventually replace the water level pressure switch, that determines when to start/stop fillng and drain.

If the drain lines are not clogged, the drain pump can be tested by reading ohms at solenoid (contacts on valve), and by energizing the pump directly.

If the pump is fine, then test the pressure switch by jumping its contacts, and advancing cycle to drain to avoid overfilling.
If you get both the codes, the cause is usually the pressure switch

Since one of the codes is overfilling, check if the inlet valve is opening and closing during the cycle, by observing if water starts and stops flowing into the machine, or by reading volts at inlet valve or at electronic control contacts. If the valve stays open or leaks with no volts from timer, then the valve is faulty. If timer is opening the valve while draining, then the timer board is probably faulty.

If water and sensor are OK, then it can be a problem with wiring or control board. Electronic control board causing this error is not common.

Test all other parts first.

You can find parts and diagrams by entering model number here.

Test and repair must be done by a trained person. Call the phone number listed on the user manual if you need to contact a qualified technician.

Regards.

Washer displays ND - not draining. Cleaned out filter, snaked drain. Still wont drain.


It is a common fault that the drain fails to work in most machines in a period of time and is the most problematic fault in a washing machine. In all occasions it is important that your observation is most important and so is vital to the identification /rectification and solution. If you have noticed that water has leaked then as the drain hose pump/valve and fittings are located on the underside of the machine it is important that you look for possible leaks here. In some cases the drain hose would be clogged at the drain end to outlet of the house and so there will be back flushing resulting in overflow to the outside. Also the drain pump/valve can be clogged. Now remove the drain hose clamps and remove the drain pump/valve, clean the drain pump/valve, use back flushing to clear off all dirt. Now test using power to see if this works and can be simulated. When refitting, the hose must be tightened properly. If the pump/valve does not work even with power then it must be replaced. If there is intermittent power to the drain valve/pump then the program controller unit is a suspect.

Finally the washer must be placed with a tilt- use a spirit level- so that all water will drain to the outlet port and thereby there is no residual water remaining.

Questions about snaking the drain line for a Bosch SHU5305. Should I be able to snake all the way from the sink connection into the dishwasher or is there some type of backflow prevention or something...


I would NOT recommend you snake into your dishwasher because you could damage the drain pump.

If you think you have blockage, then take the unit out and disconnect the drain line and take it outside and use a hose on it.

Just remember to disconnect the power first.

Water drains out as fast as it fills........but not all of the time top load Whirlpool


There is a chance the drain hose has buildup within it and needs to be cleared out. This will take about an hour.

Steps:
  • 1- Unplug the electrical cord on the washer from the wall outlet.
  • 2
  • Unfasten the hot and cold water hoses from the water lines after you shut off the water valves. Use a pair of slip-joint pliers to turn the hose fittings counterclockwise to remove them.

  • 3 Pull the washing machine far enough away from the wall so you can comfortably work on the rear of the machine.

  • 4 Locate the access panel toward the bottom left side of the back of the washer. Use a nut driver to remove the nuts that secure the access panel, and remove it.

  • 5 Find the water pump, which will have two hoses attached to it.

  • 6 Identify which hose is the drain hose by tracing it to the outside of the machine. The pump may also be labeled "Inlet" and "Outlet." The drain hose is attached to the outlet.

  • 7 Squeeze the clamp that secures the end of the drain hose to the water pump, using a pair of slip-joint pliers. Remove the end of the hose from the pump.

  • 8 Insert a plumbing snake into the end of the hose and twist the snake as you feed it through the hose. After approximately 10 feet of the snake is fed through the drain hose, you should see the snake and the clog come out the other end of the hose.

  • 9 Reattach the drain hose to the water pump and replace the access panel. Reconnect the water hoses and turn on the water valves. Push the washer back against the wall and plug in the electrical cord.

  • Hope this helps!

    remove the hose from the pump before trying. on some models there is a one way valve on the pump which will not allow air or water to be blown back into washer. This check valve may be plugged.

    Power steering presure line how to change


    Hello, to replace try this :

    1. Rotate the belt tensioner clockwise using a ratchet and socket. Then slide the drive belt off the power steering pulley. Let the tensioner pulley carefully return to the original position without snapping back to prevent damage to internal components.


    2. Place a drain pan under the vehicle to catch power steering fluid after you remove the two hoses from the steering pump.


    3. Detach the pressure hose from the steering pump by loosening the retaining nut with a flare wrench. Let the steering fluid drain into the drain pan.

    4. Loosen or slide the clamp off the return line at the steering pump (depending on the type of clamp used on your particular Taurus model). Use a ratchet and socket or a pair of slip joint pliers.Then detach the return line from the pump with your hand and let the steering fluid drain into the drain pan.

    5. Unplug the steering pump electrical connector, if your particular model is equipped with it.

    6. Remove the power steering pulley from the pump using special tool 211-016 (T69L-10300-B). For more information, see the Resources section below. Make a note of the pulley distance from the steering pump body at the mounting shaft, so that you use the same amount of clearance when you mount the pulley on the new pump.

    7. Unfasten the power steering pump mounting bolts using a ratchet, ratchet extension and socket and lift the pump off the engine compartment.

    Thanks
