If your dishwasher is not filling with water, it is often caused by a water supply issue, inlet valve fault, or restricted water flow.
While a faulty dishwasher can be a nightmare, this blog will cover the various signs your dishwasher may not be filling as well as the causes. We will also offer helpful advice towards the end to make your future decisions easier to make!
Signs Your Dishwasher Is Not Filling With Water
If your dishwasher is not filling with water, it will often not be able to progress with the cycle.
You will usually notice an error code displayed on your dishwasher or on some models, it may just stop without any sign as to why.
Certain Indesit and Hotpoint models will flash the display lights in a sequence instead of displaying a specific error code number. Most other brands such as Bosch will have specific error codes which makes the initial fault finding much easier.
If your dishwasher cannot fill with enough water, you may also find that the dishes come out dirty.
Causes & Solutions
In terms of what can cause a dishwasher not to fill with water, it is often due to one of the below reasons.
1 > The water supply is switched off or has low pressure. If your central water supply is switched off or has pressure problems, your dishwasher may not be able to fill with water effectively. We would recommend checking the stop valve under your kitchen sink and if required, calling your water company to verify the water pressure to your property is adequate.
2 > Kinked or damaged inlet hose. If your inlet hose is damaged or kinked, water will not be able to enter the appliance as it should be. Please note that certain Bosch models have an Aquatak hose, which has an electrical component. This can sometimes fail instead of the inlet hose itself being damaged or kinked. If your inlet hose is faulty, they are usually around £15 to purchase online. If you have an Aquatak inlet hose, these can be upwards of £100 depending on the length of the hose.
3 > Faulty inlet valves. In every dishwasher, there are inlet valves. These can fail and prevent water from entering the appliance. This is often a cheap fix with new inlet valves usually being priced around £30 through online retailers.
4 > Electronic problem. On some occasions, your dishwasher may not be filling with water due to a fault with the internal electronics. If you suspect this is the cause in your situation, we would recommend calling a professional as this type of cause is often case by case specific and will require different advice every time.
Can you fix this type of problem yourself without professional help?
When it comes to this type of fault, it can sometimes be repaired by you, the homeowner instead of calling a professional.
If you’re someone who is usually hands-on, you can verify whether the central water system is working properly and if the inlet hose is not damaged. Beyond this stage, we would recommend calling a professional to make the repair process easier and quicker.

Why is my dishwasher starting but not progressing with the cycle?
If your dishwasher manages to start but will not progress with the cycle, it may mean your inlet hose is kinked. During the start of the cycle, some water may be able to enter but, as it progresses and requires more and more water, the kink in the hose prevents it from continuing.
We recommend inspecting the inlet hose and ensuring that it is not damaged or kinked.
Can low water pressure cause a dishwasher not to fill?
Low water pressure can cause your dishwasher not to fill properly. It may start but will likely not progress past a certain stage of the cycle.
If you’re facing low water pressure in your property, we recommend calling your water supplier so that they can investigate and advise you accordingly.
Why do I not get an error code when my dishwasher does not fill with water?
Not all dishwasher models come with an error code system. In addition to that, certain problems like low water pressure or blockages may not trigger an error code.
Please note that if you have a Hotpoint or Indesit dishwasher, it will often display lights in a sequence instead of displaying a specific error code number.
Conclusion
To conclude, your dishwasher may not be filling with water due to a problem with your central water system, inlet hose or the inlet valves.
