If your Bosch dishwasher shows the E15 error, do not panic, this is a fairly common problem. It usually means that water has accumulated in the tray and the leak protection has been activated. This can happen, for example, due to overflow or leakage. Sometimes the E15 Bosch dishwasher error can be solved simply – just tilt the machine a little and drain the water. In other cases, cleaning or replacing parts may be required. In any case, do not rush to call a technician for Bosch appliance repair: you can often fix the error yourself. Below are simple steps that will help you deal with this problem.
General Reasons for Bosch E15 Error Code
If the Bosch dishwasher code E15 appears on the display of your unit, it means that the leakage protection sensor has been triggered. It usually reacts to the accumulation of water in the lower part of the housing. The most common reasons for E15:
-
Water leakage in the tray. This may be due to worn seals, damage to the housing, or loose connections. Water accumulates at the bottom and activates the sensor.
-
Too much detergent. If you accidentally pour too much or use the wrong detergent, foam will form, which can spill over the edges and get into the tray.
-
Clogs in the system. Dirty filters, clogged spray hoses, or drains – all prevent the normal flow of water, causing an overflow.
-
Faulty valves or hoses. Sometimes the problem is in the water supply – the valve or hose is damaged, and the water comes out uncontrollably.
-
Sensor failure. It happens less often, but still, the sensor itself is triggered by mistake.
If in doubt, it is better to call a High City Appliance repair service in Aurora, Littleton, Castle Rock, or Colorado. The expert will quickly determine the cause.
Try These Steps to Fix E15 Bosch Dishwasher Error
Before contacting the service, you can try several simple ways to fix the Bosch E15 error code. The main thing is first to disconnect the device from the power supply and turn off the water supply.
People often had this situation: the machine stopped working, and the Bosch dishwasher troubleshooting E15 lit up on the display. At first, they think it is broken, but simple steps help:
-
Power reset. Sometimes the E15 Bosch dishwasher error occurs due to a board failure. Turn off the machine for 10 minutes, then turn it on – the error disappears.
-
Too much foam. If you overdo it with detergent, foam appears, which can get into the tray. I ran a rinse without tablets – it helps.
-
Tilt. Some people advise tilting the machine back about 45 degrees – water flowed out of the tray, and the Bosch dishwasher E15 watertap message disappeared.
-
Cleaning the filters. Take out the lower basket, wash the filter, and inspect the sprayers.
If, after all this, the error remains, then the problem may be a leak or a broken sensor. You cannot do without a specialist here.
Advanced Bosch dishwasher code E15 Troubleshooting Tips
If the Bosch E15 error pump keeps running after simple actions, you have two options. First, contact the Denver appliance repair service for help, or you will have to disassemble the dishwasher a little on your own. The main thing is to turn off the power and water to avoid a short circuit or flooding. The problem is that water has accumulated in the tray, and the float sensor has been triggered. Here is what to do:
-
Disconnect the dishwasher from the network and turn off the water.
-
Remove the front bottom panel – you will need a Torx screwdriver.
-
Look into the tray – if there is water, carefully wipe it with a towel.
-
Find the white float, usually, it is foam, and dry it.
-
Check for crumbs, dirt, or broken wires near the sensor.
-
Put everything back together and turn it on.
After that, you should run a short cycle and watch if water appears again. If the Bosch E15 error code accumulates again, perhaps a hose is leaking somewhere or the inlet valve is dripping.
