Neff S513M60X1G/51 Dishwasher Won’t Go Through a Wash Cycle

August 26, 2026

Hi Paul hoping you can point me in the right direction of the part I need so I can purchase from you. Neff S513M60X1G/51 Dishwasher won’t go through a full cycle. Stop with a solid tap sign. No fault code but dishwasher is beeping. Inlet and outlet both ok, filter and sump clear of debris. I’ve put a new pump in, initially it was better but fault has re appeared. Now won’t even complete a quick rinse cycle. Matrix looks clear Hope you can help Best regards Simon.

Hi Simon,

Sorry to hear about the problem with your Neff S513M60X1G/51 dishwasher.

You didn't mention if it stopped and is still full of water. If it has, there might be something simple blocking the pump, like debris, a broken piece of glass, or some food. This is a very common issue that stops the machine from progressing.

Here are a few questions to help figure out what's going on with your Neff S513M60X1G/51:

Is the machine spraying water inside? If the machine fills but doesn't wash, there could be a motor problem (either an open circuit in the main wash motor or a fault on the circuit board failing to send power to it).
Is it heating? If the wash starts but never finishes, or fails to clean properly, a faulty heating element or thermostat could be the issue.
When does it pause? The "stop water" light shows there's a general problem but doesn't specify what. If the machine stops shortly after starting and fills with water but then pauses before washing, the impeller jug or water flow matrix might be blocked or faulty.

⚠️ Crucial Tip: Watch the Videos! I have included a couple of videos below, and I strongly recommend you watch them fully. The first video explains a critical diagnostic tool: using a simple watt/amp meter plug to understand exactly what your dishwasher is doing. For instance, if your machine is filled with water but not spraying, a meter will tell you if the main motor is drawing its normal 70 watts of power or if it’s completely dead. It also lets you see if the 1650-watt heating element actually kicks in. It’s an essential tool that saves hours of guesswork! The second video shows how grease, grime, and debris can build up in the pressure bowls and pipes, tricking the machine into thinking it's full (or empty) when it isn't. It shows you exactly how to strip these parts down and clear the blockages.

I've also included some diagrams on this page to help you locate these parts. There is a test meter linked at the top of the page—as shown in the video, it is a very important tool to have nowadays to read the ampage and wattage as the machine washes.
