Error codes are model dependent, so the same brand may have more than one listed.
| Code | Brand | What it means | Confidence |
|---|---|---|---|
| E18 | Bosch | Means a drainage failure, where the machine cannot empty water within the allowed timeframe. It is usually caused by a blocked drain pump filter or a kinked hose. | High |
| E2 | Bosch | Means a drainage failure that stops the machine mid-cycle because water is not emptying within the required time. It is usually caused by a blocked pump filter, a kinked drain hose, or a failed drain pump. | High |
| E20 | Bosch | Means a drainage problem where the machine cannot empty water and stops the cycle to prevent flooding. It is usually caused by a blocked filter, an obstructed pump, or a kinked drain hose. | High |
| E28 | Bosch | Means a flow sensor fault, where the water is not draining properly or the sensor cannot detect water flow correctly. It is usually caused by a malfunctioning turbidity sensor (dirty water sensor) or a drainage blockage. | Medium |
| E4 | Bosch | Means a drainage failure. It is usually caused by a blocked pump filter, a kinked drain hose, or a faulty drain pump. | High |
| F3 | Bosch | Means a drainage failure, where the machine has not emptied water within a set time. It is usually caused by a blocked pump, filter, or hose. | High |
| F5 | Bosch | Means a drainage failure where the machine cannot empty water, or on certain models a motor fault. It is usually caused by a blocked filter, an obstructed drain hose, a faulty drain pump, or worn carbon brushes. | High |
| F7 | Bosch | Means a drainage system fault that prevents water from emptying and triggers a door lock safety issue. It is usually caused by a blockage in the filter or drain hose. | High |
| F8 | Bosch | Means a drainage problem. It is usually caused by a bent pipe connected to a pressure sensor, or debris or mechanical failure in the drain pump. | High |
| F9 | Bosch | Means a drainage failure where the machine cannot drain water, causing it to stop mid-cycle. It is usually caused by a blocked pump filter, clogged hoses, or a faulty drain pump. | High |
| E12 | Siemens | Means the machine cannot empty water properly. It is usually caused by a blocked drain filter, an obstructed drain hose, or a faulty drain pump. | High |
| E18 | Siemens | Means the machine has failed to drain. It is usually caused by a blocked drain pump, a clogged filter, or a kinked drain hose. | High |
| E2 | Siemens | Means the machine cannot detect that the door is securely closed, or it is unable to drain water. It is usually caused by a faulty door lock or a drain pump that is not operating. | Medium |
| E21 | Siemens | Means the machine cannot empty water within the time allowed, taking too long to drain and prompting a shutdown to prevent flooding. It is usually caused by a blocked pump filter, an obstructed drain hose, or a faulty drain pump. | High |
| E23 | Siemens | Means the AquaStop system has activated because water has leaked onto the base plate. It is usually caused by a leaking connection, a damaged hose, a jammed filter, or a pump that is not operating. | Medium |
| E3 | Siemens | Means the appliance is not draining water properly. It is usually caused by a blocked drain pump, a clogged filter, or a kinked hose. | High |
| E30 | Siemens | Means there is a problem with the drainage system, with the outlet hose connected too high, kinked, trapped, or extended too far, or the drain pipe or outlet hose blocked. It is usually caused by a displaced or blocked drain hose. | High |
| E35 | Siemens | Means water has leaked into the base of the machine and activated a flood safety switch, locking the door and stopping the machine. It is usually caused by a pressure switch fault or an overfill issue. | Medium |
| E36 | Siemens | Means the machine cannot empty water within the time allowed. It is usually caused by a blocked filter, an obstructed drain hose, or a faulty pump. | High |
| E4 | Siemens | Means water is not draining from the machine, or the door is not locked properly so the cycle cannot run. It is usually caused by a blocked filter or pump, or a door that is not locking. | High |
| E6 | Siemens | Means the machine cannot empty water within the designated time. It is usually caused by a blocked pump filter, a kinked drain hose, or a faulty drain pump. | High |
| E8 | Siemens | Means there is a drainage failure, water pump issue, or water level error. It is usually caused by blocked supply hoses or filters, or a drain pump that is not operating. | High |
| E81 | Siemens | Means the door mechanism is faulty and preventing unlocking, or the pump cannot drain water, stopping the cycle from finishing. It is usually caused by a faulty door lock or a blocked drain pump. | Medium |
| F3 | Siemens | Means the machine has not emptied water from the drum within the expected time, often stopping mid-cycle with water still inside. It is usually caused by a blockage, a drain pump that is not operating, or a jammed filter. | High |
| F7 | Siemens | Means there is a motor fault or a failure to reach the correct speed during a cycle, which often cuts out the spin, or on some models a door lock issue. It is usually caused by a motor fault, a pump that is not operating, or a door that is not locking. | Medium |

Compatible Bosch Washing Machine Pump Motor. This pump motor fits to your existing pump housing with a 3 bayonet type fitting.
Notice - This pump is a 3 bayonet type fitting. If your existing pump has a 4 bayonet type fitting then order RS121818
My Bosch Excel washing machine stopped working with water in the drum and an error code indicating a pump or filter problem, which was isolated to the pump. This replacement was easy to find on the Ransom Spares website with confidence it would fit my machine. The part arrived swiftly and was easily fitted as it was an exact match with the electrical connector, inlet and outlet and filter bayonet in the identical positions as the original part.
I gave my full model number, The part I received wasn’t compatible for my machine so I had to reorder new part all to getter with the link which was send to me by one of your customer service agent which works but it seems their is other problem I have send return new part waiting for refund money back to credit card overall very satisfied with service
Found this pump very easy to fit, with only a torx driver and a set of pliers, with it taking no more than 20 minutes including manoeuvring the machine out and back in again. The pump is working well and the machine is happy again, all for less than 20 quid, including next day delivery. Very pleased indeed!
Ordered this to replace the pump on my Siemens XLP1400 washing machine. The original had lasted well at 15 years and this compatible pump was a lot cheaper that the Siemens original. Fitting was hampered by the fact that the machine has an anti-flood base which is pop riveted in place so the new pump had to be fitted through the rear which is awkward to say the least. In the end I removed the complete filter body and pump as one item and then split them. This is also a bit fiddley due to having to remove two hoses which have very tight spring clips holding them on. The easiest way to replace the pump if access is easy, which it may be on other models, is to remove the electrical connector and the screw on the left of the pump (which locks it in place) and twist the pump anticlockwise a few degrees. It just pulls off. Refitting is just a matter of inserting the pump and twisting it clockwise a few degrees and replacing the screw. You need to make sure that all three locating lugs are engaged correctly or you will get a massive leak (experience - oops!) and replace the screw and electrical connector. Its all now fitted and working well.
Had a lot of trouble finding a pump for the European model Bosch. Ranson spares were the only people who came back with an answer. The machine is 15 years old so didnt want to risk the £60 on original equipment (also from Ransom) so bought the cheap aftermarket replacement which i was not sure would fit. However was a perfekt fit and works well. Should note that the amps are 0.3 not 0.2 as the original.
