Note: It is your responsibility to ensure you are wearing the appropriate PPE: gloves, eye protection and mask when handling chemicals or cleaning your machine. When working with detergent and chemicals, always make sure you have familiarised yourself with the COSHH safety datasheets beforehand.
If your dishwasher isn’t working properly but you’re not sure why, the first point of troubleshooting is to drain the machine down, turn off, take apart and clean.

Possible Causes
1. Low detergent levels
First thing's first - have you checked the detergent levels? And are you using a detergent and rinse aid suitable for your dishwasher?
Did you know HOBART have our very own dishwasher chemicals range? Specifically formulated for HOBART commercial dishwashers, our Hyline range includes detergents (soft water and hard water), rinse aid, dishwasher salt and hygiene tablets for your machine's Hygiene Cycle.

2. Blocked detergent hoses
See 'How to unblock my detergent hoses' below.
3. Airlock in detergent hoses
See 'How to unblock an airlock in my detergent hoses' below.
4. Your dishwasher may need a deep clean
See 'How to deep clean my dishwasher' below.
If your dishwasher has been out of use for a considerable amount of time or wasn’t shut down properly, the chemical or detergent hoses may be blocked with crystalised detergent.
Here’s how to flush the hoses through to unblock.
First try to pull detergent through the hoses to dislodge the blockage, this is called 'Priming the detergent lines'. Leave the hoses in the detergent bottles and follow these instructions on the touch screen display.
If this doesn’t work, try flushing with warm water:
Firsty, ensure you are wearing adequate PPE and feel confident to do so.
Take the hoses out of the detergent bottles and drop into a bucket of hot water (hot tap water will be fine, do not use boiling water). Then repeat the process with the hot water:
Have the hoses unblocked?
Yes: Great! Now you’ll need to prime the lines again with detergent: pop the hoses back into the chemicals, follow the above process again and you’re good to go.
No: Still blocked? Try repeating the process again.
Still no luck? Give our team a call on 01733 392237 and we’ll get a local Service Technician out to you urgently.
Note: These instructions may vary, depending on the model of dishwasher you're working on. If unsure, please refer to your manual.
If your machine has been out of action for a while - or if you've run out of detergent and continued using your machine - there may be an airlock in detergent hoses and you'll need to prime the detergent lines.
Here’s how to flush the hoses through to unblock an airlock.
Leave the hoses in the detergent bottles and follow these instructions on the touch screen display.
If this doesn't work, try following the additional steps in 'How do I unblock my detergent hoses?' as there may be another source of blockage.
Still no luck? Give our team a call on 01733 392237 and we’ll get a local Service Technician out to you urgently.
If your dishwasher isn’t draining properly, it is usually due to a blockage. Due to the nature of blockages, it’s best to call out a Service Technician to deal with the issue.
If your kitchen is going to be closed for a day or more, it is crucial to shut the machine down correctly. This includes draining the machine down to ensure there’s no standing water and potential debris left inside which could cause blockages at a later date. If the dishwasher is not shut down correctly, this is a potential environment for harmful bacteria.
Once our Technician has fixed your machine, you’ll need to run a Hygiene Cycle. See ‘How do I deep clean a commercial dishwasher?’ for step-by-step instructions on running a Hygiene Cycle.
Give our team a call on 01733 392237 and we’ll get a local Service Technician out to you urgently.
It’s important to deep clean any dishwasher to ensure optimised functionality and to kill any harmful bacteria in your machine.
If your dishwasher has been out of action over the lockdown period, it is essential you give it a deep clean before reopening your business.
Most HOBART dishwashers flag up on the display screen when a Hygiene Cycle is needed. For any machines that don’t have this feature, we recommend a monthly deep clean to keep bacteria at bay.
To prepare your dishwasher for the Hygiene Cycle:
It’s now important to give the machine a quick rinse through before putting it into a Hygiene Cycle. This will remove any loose salt, missed debris.
The very last thing we do is run the Hygiene Cycle. This cycle works best with HOBART’S Hyline Hygiene Tablets.
To start the Hygiene Cycle:
After the Hygiene Cycle is complete, drain and refill the dishwasher prior to putting the machine back into service.
