What Er:13 means on a Thermador range

Er:13 on a Thermador WFR 2460 washer-equipped range indicates that the water inlet cycle has exceeded its allowed time limit. This fault is specifically tied to the water fill system, where the control board monitors how long it takes for water to reach the appropriate level or complete the fill sequence. When the inlet time surpasses the programmed threshold, the board logs Er:13 and halts operation to prevent overflow or component damage. The fault is attributed to either a sensor problem or an issue within the water supply line itself.

The two primary subsystems involved are the water inlet line (including the supply connection, inlet valve, and any associated filters or screens) and the water level or flow sensor that reports fill status back to the control board. If the sensor is faulty or reading incorrectly, the board may believe the fill cycle is incomplete even when sufficient water has entered. Conversely, if there is a physical restriction in the supply line or the inlet valve is not opening fully, the actual fill rate may be too slow to complete within the allowed window.

The correct starting point for diagnosis is T/P 11, the dedicated sensor test programme. Running this test allows the technician to evaluate whether the sensor is responding correctly under controlled conditions. If the sensor passes, attention shifts to the mechanical side: checking water pressure at the supply, inspecting the inlet valve for proper operation, and examining the line for kinks, blockages, or mineral buildup that could restrict flow and cause the inlet time to be exceeded.

Common causes of Er:13

  1. 01

    Restricted or kinked water supply line

    Wiring / connection

    A kinked hose, partially closed shutoff valve, or mineral deposits inside the supply line can reduce water flow enough that the fill cycle cannot complete in time. Check the inlet line for physical restrictions and verify the shutoff valve is fully open.

  2. 02

    Clogged inlet valve screen or filter

    Wiring / connection

    Sediment and mineral buildup can accumulate on the mesh filter screen at the water inlet valve, significantly reducing flow rate. Inspect and clean the screen or replace the inlet valve assembly if the screen is damaged.

  3. 03

    Faulty water level or flow sensor

    Part replacement

    If the sensor that reports fill status to the control board is malfunctioning, it may signal that the fill is incomplete even when the unit has received adequate water. Run the T/P 11 sensor test programme to evaluate sensor response.

  4. 04

    Defective water inlet valve

    Part replacement

    The solenoid-operated inlet valve may not be opening fully due to a failing solenoid coil or a worn valve seat, restricting water flow below the rate required to meet the fill deadline. Test the valve for proper actuation and flow output.

  5. 05

    Insufficient household water pressure

    Wiring / connection

    If the incoming water pressure from the home supply is too low, the fill rate may be adequate under normal conditions but fall short of what the range requires within the allowed time window. Check supply pressure at the connection point.

Frequently asked questions about Er:13

What does Er:13 mean on a Thermador range?
Er:13 means the water inlet fill cycle took longer than the allowed time to complete. The range monitors how long it takes water to reach the required level, and when that time limit is exceeded, the control board logs this fault and stops operation. The cause can be a restricted water supply line, a clogged inlet valve screen, low water pressure, or a faulty water level sensor. The first diagnostic step is to run the T/P 11 sensor test programme.
Can I fix Er:13 on my Thermador range myself?
Some causes of Er:13 are DIY-friendly, such as checking and straightening the water supply hose, opening a partially closed shutoff valve, or cleaning a clogged inlet screen. However, diagnosing a faulty sensor or replacing the water inlet valve requires running the T/P 11 test programme and working with the water supply connection, which may be better suited to a qualified technician if you are unfamiliar with appliance repair.
Is it safe to keep using my Thermador range when Er:13 is showing?
You should not attempt to bypass or continue running water-dependent functions when Er:13 is active. The error exists to prevent overflow or damage that could result from an uncontrolled fill cycle. Address the underlying cause before resuming operation of the water-related features.
Will resetting my Thermador range clear the Er:13 code?
A power reset may temporarily clear the displayed fault code, but if the underlying issue with the water supply line or sensor has not been resolved, the error will return as soon as the fill cycle is attempted again. A proper repair of the root cause is required to permanently clear Er:13.
How much does it cost to repair an Er:13 fault on a Thermador range?
Repair costs vary depending on the cause. If the fix involves only cleaning an inlet screen or adjusting the supply line, costs may be minimal. Replacing a water inlet valve typically costs in the range of $80 to $200 for parts alone, while a sensor replacement can fall in a similar range. Professional labor for diagnosis and repair generally adds $100 to $250 or more depending on your location and the complexity of the repair.
