Error codes are model dependent, so the same brand may have more than one listed.
| Code | Brand | What it means | Confidence |
|---|---|---|---|
| E19 | Bosch | Means a heat exchanger fault affecting the recirculation valve (also called the outlet valve), or a fault where the dishwasher cannot drain water properly. It is usually caused by a faulty recirculation valve or a drainage problem at the pump. | Medium |
| E21 | Bosch | Means a circulation pump or drainage fault that stops the dishwasher mid-cycle or prevents it draining. It is usually caused by a blockage, debris in the pump impeller, or a faulty pump motor. | Medium |
| E22 | Bosch | Means a drainage fault, often with standing water at the bottom. It is usually caused by food particles, grease, or debris clogging the internal filter, or a kinked drain hose. | High |
| E24 | Bosch | Means a drainage fault, often appearing with standing water in the tub or a humming noise. It is usually caused by a blocked filter, a clogged drain hose, or a loose pump cover. | High |
| E15 | Neff | Means water has leaked into the base tray and triggered the anti flood safety switch, leaving the pump running continuously. It is usually caused by a failed sump seal, loose hoses, or a false alarm from suds. | High |
| E17 | Neff | Means the water level inside the appliance is too high. It is usually caused by excessive water intake, a blockage, a drainage fault, or excessive detergent suds. | Medium |
| E22 | Neff | Means a blocked or dirty filter is preventing proper drainage, leaving residual water in the sump. It is usually caused by a blocked filter, a blocked drain pump, or a kinked drain hose. | High |
| E23 | Neff | Means there is a drainage fault with the pump jammed by food debris or glass and unable to remove water. It is usually caused by a blocked drain pump, clogged filters, or a kinked drain hose. | High |
| E24 | Neff | Means there is a drainage fault preventing the machine from emptying. It is usually caused by a blocked drain pump, clogged filters, a kinked drain hose, a loose pump cover, or a blocked hose under the sink. | High |
| E15 | Siemens | Means water has leaked into the base pan, triggering the anti-flood sensor and causing the drain pump to run continuously. It is usually caused by excessive suds, clogged filters, or a leaking hose. | High |
| E18 | Siemens | Means there is a drainage fault or a water supply issue. It is usually caused by a blocked filter, an obstructed drain pump, or a kinked drain hose. | High |
| E20 | Siemens | Means there is a drainage problem or a fault with the pump that moves water around during the wash. It is usually caused by a clogged filter, a clogged drain pump, or a blockage in the pump. | High |
| E21 | Siemens | Means the drain pump or circulation pump is jammed, obstructed, or failing. It is usually caused by food debris, broken glass, or crystallised dishwasher salt blocking the drain pump, filter, or hose. | High |
| E22 | Siemens | Means there is a drainage blockage or soiled filter system, often stopping the cycle mid-way. It is usually caused by food residue or excessive soap buildup. | High |
| E24 | Siemens | Means water is not draining from the machine. It is usually caused by a blocked drain pump, a clogged filter, or a kinked hose. | High |
| E3 | Siemens | Means the unit cannot reach the required water level in the allotted time, with a drainage issue or a water level sensor problem preventing it from filling correctly. It is usually caused by a blocked filter, a drain pump that is not operating, or a blocked spray arm. | High |
| E4 | Siemens | Means water is not draining properly or an overflow has occurred. It is usually caused by clogged filters, a blocked drain pump, or a kinked drain hose. | High |
| E4 | Whirlpool | Means a water overflow or leak in the base pan has tripped the anti-flood float switch and shut the machine down, shown as F8E4. It is usually caused by an internal leak, a door not sealing, or a blocked filter. | High |
| F9 | Whirlpool | Means the unit cannot remove water or has a continuous fill fault, displayed as F9E1 and may stop mid-cycle with error lights and a beep. It is usually caused by a blocked filter, a drainage fault, continuous filling, a faulty pump, or a faulty control board. | High |
