E17 Error: If your Bosch dishwasher is displaying E17 on the control pa

If your Bosch dishwasher is displaying E17 on the control panel, it's detected that water inside the machine is getting too hot. This is a safety mechanism designed to prevent damage to your dishes and the appliance itself. The error indicates a fault with the thermostat system—essentially, your dishwasher can't regulate water temperature properly or is receiving incorrect temperature readings. The good news is that E17 faults are often straightforward to resolve, and many homeowners successfully fix them without calling an engineer. The issue typically stems from one of two components: either the NTC temperature sensor has failed and is sending dodgy signals to the control system, or the main control module (PCB) has developed a fault that's preventing it from reading temperature data correctly. Before you panic about repair costs, it's worth noting that the temperature sensor is usually an affordable and relatively simple replacement. However, diagnosing which component is actually faulty does require some careful investigation. This guide will walk you through the troubleshooting process, helping you identify the culprit and decide whether you're confident tackling the repair yourself or need professional assistance.

NTC Temperature Sensor

OEM: 00171260

# NTC Temperature Sensor for Bosch and Siemens Dishwashers When your dishwasher fails to heat water properly or displays temperature-related error codes, a faulty temperature sensor is often the culprit. This NTC Temperature Sensor (OEM reference 00171260) regulates water temperature throughout the wash cycle, ensuring your dishes come out spotlessly clean. Without it functioning correctly, your appliance simply cannot perform its job effectively. This genuine part is designed for Bosch and Siemens dishwashers and handles general wear and failure that occurs naturally over time. Replacing it is a straightforward task rated at difficulty level 2, making it manageable for most home DIYers without specialist training. When installing your new sensor, take time to ensure the connector sits fully and firmly in place, as loose connections are a common cause of recurring issues. This simple precaution can save you troubleshooting headaches down the line. Before ordering, verify your dishwasher's E-Nr model number matches this part's compatibility to guarantee a perfect fit and smooth replacement. This reference number is typically found inside the door edge or on the appliance's data plate.

Main Control Module (PCB)

OEM: 00648858

# Main Control Module (PCB) If your Bosch or Siemens dishwasher has stopped responding to button presses, won't cycle through programmes, or displays error codes, a faulty control module is likely the culprit. This component manages all the appliance's functions, so when it fails through age or electrical damage, your dishwasher becomes unusable. This replacement Main Control Module, reference 00648858, restores full functionality to compatible Bosch and Siemens models. It's a moderately challenging repair job, rated 4 out of 5 for difficulty, so expect to spend a couple of hours on installation if you're reasonably handy. Before you begin, take a photograph of the control panel layout and any cable connections. This simple step saves frustration when reassembling, as the module involves multiple electrical connections that must be correctly positioned. Modern control modules are precision components, so handle yours carefully throughout the installation process to avoid damage. Always verify your dishwasher's E-Nr model number matches the compatibility list before ordering. You'll find this on the appliance's data plate, usually inside the door edge. Ordering the wrong part wastes time and money, so take a moment to check first.
