it could be a part is damaged or broken or a timing problem,,it
would be a good idea to have the machine checked.

there is a filter in the injector pump, under the inlet line. could be blocked.

also try cracking the injector line and cranking the car to bleed the lines.

you need to release front points, they are partialy ceized, penatrating oil (wd40) keep working them, plenty of patience needed. good luck

Make sure the water is turned off to system. Open the faucet to system to drain any water and keep the faucet turned on to keep pressure off filter housings.
1.Use the wrench to take housings off.
2. If they still won't budge take a small 2x4 block of wood and hammer, set the block of wood on the RIB for the housing and tap with hammer.
3. Change the o-rings in both housings, lubricate with silicone lube and lubricate the threads on housings with silicone also.
3. Rinse housings with small amount of bleach and clean thoroughly.
4. Replace filters and housings.
5. IMPORTANT: Only tighten housings by hand. NEVER tighten housings with wrench.

Somebody over tightened the filter. Your only choice is to force it to turn in any way possible. I've had to resort to sticking a screw driver through the filter to get enough torque to remove them. Good luck

Push button? It should be a turn to the left to remove if it is a whirpool located at the bottom. These are twist out not push to release. The only push to releases are made by electrolux.
